7783-06-4 Usage

General Description

Hydrogen sulfide is a colorless, flammable, and highly toxic gas known for its characteristic foul smell of rotten eggs. It is produced by bacterial breakdown of organic material and human/animal wastes, as well as natural processes such as volcanic activity. Its formula is H2S. It is heavier than air and can accumulate in low-lying areas. Exposure to high concentrations can cause severe health effects, such as respiratory irritation, loss of consciousness, and even death. In the environment, it can contribute to acid rain. It is also used in several industrial applications, including the production of sulfuric acid and sulfur, food processing, and as an additive in natural gas.

Check Digit Verification of cas no

The CAS Registry Mumber 7783-06-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7783-06:
(6*7)+(5*7)+(4*8)+(3*3)+(2*0)+(1*6)=124
124 % 10 = 4
So 7783-06-4 is a valid CAS Registry Number.

LATTICE VIBRATION SPECTRA Part LXIV. Raman spectroscopic study of lithium hydrogensulfide LiSH: dynamic disorder and order-disorder phase transition

Beckenkamp, K.,Lutz, H. D.,Jacobs, H.,Metzner, U.

, p. 203 - 213 (1991)

Raman spectra (4000-50 cm-1) of lithium hydrogensulfide are recorded in the range from 70 to 300 K.The temperature dependence of frequencies and halfwidths of the SH- stretching and librational modes yields clear evidence for a disorder-order phase transition at 222 K and thermally activated dynamic disorder of the SH- ions in the room temperature polymorph.Down to 70 K the increasing splitting of the in-plane libration can be interpreted by a Landau-type order parameter.This splitting reflects increasing dynamic interactions (factor group splitting) of adjacent (in ) SH- ions due to the ordering process.The halfwidths of the stretching and out-of-plane librational modes exhibits an Arrhenius-type behaviour.The activation energies derived are 1.9 kJ mol-1 for both vibrations.The activation temperature (230 K) is in good agreement with that of the change of the specific heat at 228 K.The order mechanism and a plausible structure of the ordered phase below 222 K are discussed.

Sulfur-33 Isotope Tracing of the Hydrodesulfurization Process: Insights into the Reaction Mechanism, Catalyst Characterization and Improvement

Sushkevich, Vitaly L.,Popov, Andrey G.,Ivanova, Irina I.

, p. 10872 - 10876 (2017)

The novel approach based on 33S isotope tracing is proposed for the elucidation of hydrodesulfurization (HDS) mechanisms and characterization of molybdenum sulfide catalysts. The technique involves sulfidation of the catalyst with 33S-isotope-labeled dihydrogen sulfide, followed by monitoring the fate of the 33S isotope in the course of the hydrodesulfurization reaction by online mass spectrometry and characterization of the catalyst after the reaction by temperature-programmed oxidation with mass spectrometry (TPO-MS). The results point to different pathways of thiophene transformation over Co or Ni-promoted and unpromoted molybdenum sulfide catalysts, provide information on the role of promoter and give a key for the design of new efficient HDS catalysts.

Polymersome Wound Dressing Spray Capable of Bacterial Inhibition and H2S Generation for Complete Diabetic Wound Healing

Liu, Danqing,Liao, Yuyao,Cornel, Erik Jan,Lv, Mingchen,Wu, Tong,Zhang, Xinyue,Fan, Liujie,Sun, Min,Zhu, Yunqing,Fan, Zhen,Du, Jianzhong

, p. 7972 - 7985 (2021/11/01)

Diabetic wounds are difficult to heal due to recurrent bacterial infection, decreased proliferation, and migration of epidermal and endothelial cells. This is related to impaired leukocyte function and low blood concentrations of H2S in diabetic patients. Herein, an antibacterial polymersome-based wound dressing spray was demonstrated for complete diabetic wound healing. The designed polymersome was self-assembled from poly(?-caprolactone)24-block-poly[lysine15-stat-(S-aroylthiooxime)23] [PCL24-b-P(Lys23-stat-SATO15)], where PCL is the hydrophobic membrane-forming block and P(Lys-stat-SATO) acts as a hydrophilic stabilizer block. The polymersomes can penetrate and kill Gram-positive and Gram-negative bacteria because of the electrostatic interaction induced by the antibacterial P(Lys23-stat-SATO15) block. Furthermore, the SATO segments are capable of long-term H2S generation by reacting with cysteine (up to 12 h). This promotes proliferation, migration of epidermal and endothelial cells, and angiogenesis. Overall, this polymersome-based wound dressing spray acts as a bacterial inhibitor and H2S generator and offers a fresh insight into the effective treatment of diabetic wounds.

N-Methylation of Self-Immolative Thiocarbamates Provides Insights into the Mechanism of Carbonyl Sulfide Release

Levinn, Carolyn M.,Mancuso, Jenna L.,Lutz, Rachel E.,Smith, Haley M.,Hendon, Christopher H.,Pluth, Michael D.

, p. 5443 - 5451 (2021/05/07)

Hydrogen sulfide (H2S) is an important biomolecule, and self-immolative thiocarbamates have shown great promise as triggerable H2S donors with suitable analogous control compounds; however, thiocarbamates with electron-deficient payloads are less efficient H2S donors. We report here the synthesis and study of a series of N-methylated esterase-triggered thiocarbamates that block the postulated unproductive deprotonation-based pathway for these compounds. The relative reaction profiles for H2S release across a series of electron-rich and electron-poor N-Me aniline payloads are examined experimentally and computationally. We show that thiocarbamate N-methylation does block some side reactivity and increases the H2S release profiles for electron-poor donors. Additionally, we show that isothiocyanate release is not a competitive pathway, and rather that the reduced efficiency of electron-poor donors is likely due to other side reactions.

In Vitro Reconstitution of a Five-Step Pathway for Bacterial Ergothioneine Catabolism

Beliaeva, Mariia A.,Leisinger, Florian,Seebeck, Florian P.

, p. 397 - 403 (2021/03/08)

Ergothioneine is a histidine-derived sulfur metabolite that is biosynthesized by bacteria and fungi. Plants and animals absorb ergothioneine as a micronutrient from their environment or nutrition. Several different mechanisms of microbial ergothioneine production have been described in the past ten years. Much less is known about the genetic and structural basis for ergothioneine catabolism. In this report, we describe the in vitro reconstitution of a five-step pathway that degrades ergothioneine to l-glutamate, trimethylamine, hydrogen sulfide, carbon dioxide, and ammonia. The first two steps are catalyzed by the two enzymes ergothionase and thiourocanate hydratase. These enzymes are closely related to the first two enzymes in histidine catabolism. However, the crystal structure of thiourocanate hydratase from the firmicute Paenibacillus sp. reveals specific structural features that strictly differentiate the activity of this enzyme from that of urocanate hydratases. The final two steps are catalyzed by metal-dependent hydrolases that share most homology with the last two enzymes in uracil catabolism. The early and late part of this pathway are connected by an entirely new enzyme type that catalyzes desulfurization of a thiohydantoin intermediate. Homologous enzymes are encoded in many soil-dwelling firmicutes and proteobacteria, suggesting that bacterial activity may have a significant impact on the environmental availability of ergothioneine.
