764-85-2 Usage

Chemical Properties

clear slightly yellow liquid


Nonanoyl chloride is used for the acylation of amine groups of chitosan to simultaneously improve its material properties and adsorption capacity. It was also used in the synthesis of N-nonanoyl piperonylamide, caged vanilloid, N-(4-hydroxy-3-methoxybenzyl)-N-(2-nitrobenzyl)-nonanoylamide or N-(2-Nitrobenzyl)-N-vanillyl-nonanoylamide, n-benzylnonanamide.

Purification Methods

Reflux it with acetyl chloride (~ 3 volumes) for 1hour, then distil off AcCl followed by the nonanoyl chloride at ~12mm. It is moisture sensitive and should be stored in sealed ampoules. [Beilstein 2 IV 1023.]

Check Digit Verification of cas no

The CAS Registry Mumber 764-85-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,6 and 4 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 764-85:
92 % 10 = 2
So 764-85-2 is a valid CAS Registry Number.

Pseudotrienic acids A and B, two bioactive metabolites from Pseudomonas sp. MF381-IODS

Pohanka, Anton,Broberg, Anders,Johansson, Maria,Kenne, Lennart,Levenfors, Jolanta

, p. 1380 - 1385 (2005)

Bioassay-guided fractionation of the liquid culture broth of Pseudomonas sp. MF381-IODS yielded two new antimicrobial substances, identified as (2E,4E,6E)-9-[((2S,3R)-3-hydroxy-4-{(3E,5E,7RS)-7-hydroxy-4-methylhexadeca-3, 5-dienoyl]amino}-2-methylbutanoyl)amino]nona-2,4,6-trienoic acid and the tetradeca equivalent, named pseudotrienic acids A (1) and B (2), respectively. The compounds are prone to lactone formation, and their structures suggest them to be derived from ring opening of a macrolide. Pseudotrienic acids A and B inhibited growth of Staphylococcus aureus (MIC 70 μg/mL) and Pseudomonas syringae pv. syringae (MIC 70 μg/mL). Two known antimicrobial compounds, the polyketide 2,3-deepoxy-2,3-didehydrorhizoxin (3) and the tryptophan-derived pyrrolnitrin (4), were also identified.

Benzimidazole tethered thioureas as a new entry to elastase inhibition and free radical scavenging: Synthesis, molecular docking, and enzyme inhibitory kinetics

Abbas, Qamar,Ashraf, Saba,Channar, Pervaiz Ali,Hassan, Abbas,Hassan, Mubashar,Rafique, Hummera,Raza, Hussain,Rind, Mahboob Ali,Saeed, Aamer,Seo, Sung-Yum,Ujan, Rabail,Ul-Hamid, Anwar

The porcine pancreatic elastase inhibition and free-radical scavenging play a crucial role in age progression. All the series of 10 newly synthesized benzimidazole thioureas (4a-j) were assessed for elastase inhibition and radical scavenging activity to identify the suitable anti-aging ingredient for cosmetics products. The compounds 4e, 4f, 4g, and 4h showed inhibition better than the standard, while compound 4f showed the most significant elastase inhibition with the IC50 value of 1.318 ± 0.025 μM compared with oleanic acid IC50 13.451 ± 0.014 used ±1.989 and 41.563 ± 0.824, respectively, as standard. Molecular docking studies were performed and the compound 4f showed binding energy of 7.2 kcal/mol. Kinetics studies revealed inhibition of the pancreatic elastase in a competitive manner. The relative binding energy and structure activity relationship (SAR) identified compound 4f as an effective inhibitor of porcine pancreatic elastase. Compounds 4e and 4i showed remarkable free-radical scavenging activity with SC50 values of 26.421.

Neutrophil-Selective Fluorescent Probe Development through Metabolism-Oriented Live-Cell Distinction

Gao, Min,Lee, Sun Hyeok,Park, Sang Hyuk,Ciaramicoli, Larissa Miasiro,Kwon, Haw-Young,Cho, Heewon,Jeong, Joseph,Chang, Young-Tae

Human neutrophils are the most abundant leukocytes and have been considered as the first line of defence in the innate immune system. Selective imaging of live neutrophils will facilitate the in situ study of neutrophils in infection or inflammation events as well as clinical diagnosis. However, small-molecule-based probes for the discrimination of live neutrophils among different granulocytes in human blood have yet to be reported. Herein, we report the first fluorescent probe NeutropG for the specific distinction and imaging of active neutrophils. The selective staining mechanism of NeutropG is elucidated as metabolism-oriented live-cell distinction (MOLD) through lipid droplet biogenesis with the help of ACSL and DGAT. Finally, NeutropG is applied to accurately quantify neutrophil levels in fresh blood samples by showing a high correlation with the current clinical method.
