General Description

9H-Carbazole, 1-nitro- is a chemical compound with the molecular formula C12H8N2O2. It is a nitro derivative of carbazole, which is a heterocyclic aromatic compound commonly used in the production of dyes and pigments. 9H-Carbazole, 1-nitro- is primarily used as an intermediate in the synthesis of various organic compounds, including pharmaceuticals and agrochemicals. It is a pale yellow crystalline solid that is sparingly soluble in water but more soluble in organic solvents. 9H-Carbazole, 1-nitro- may have potential applications in the field of organic chemistry and material science due to its unique chemical properties and structure. It is important to handle and store this chemical with caution, as it may pose health and environmental hazards if not properly managed.

Check Digit Verification of cas no

The CAS Registry Mumber 31438-22-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,4,3 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 31438-22:
(7*3)+(6*1)+(5*4)+(4*3)+(3*8)+(2*2)+(1*2)=89
89 % 10 = 9
So 31438-22-9 is a valid CAS Registry Number.

Carbazole N-substituent effect upon DTMA: Stabilizing and photochromic modulating

Huo, Zhiming,Li, Zhipeng,Wang, Tingting,Zeng, Heping

supporting information, p. 8964 - 8973 (2013/09/23)

Dithienylmaleimide derivatives 7-27 were synthesized by introducing N-substituted carbazole for photo-stabilizing purpose, and the structures were fully confirmed. The photochromism and photo-stability were recorded via UV-vis spectra. Only ortho compounds 8-17 with N-substituents on carbazole moiety showed escalated photochromic change, while compound 7 and the para counterparts 18-27 showed no appreciable photochromism. Additionally, compounds 8-18 exhibited good photo-stability except 17 under 254 nm irradiation. The unstability of 17 may probably due to overrunning hindrance. These photochromic patterns indicated that hindrance and electronic effect mutually paid a decisive influence on the photochromism and photo-stability, which potentially exploited a new way to construct novel photochromic materials with regulable and conceivable performance.

Synthesis and isolation of nitro-β-carbolines obtained by nitration of commercial β-carboline alkaloids

Ponce,Erra-Balsells

, p. 1071 - 1082 (2007/10/03)

Nitration of commercial full aromatic β-carboline alkaloids nor-harmane (1), harmane (2), harmine (3), harmol (4), and the 7-acetylated derivative of harmol (5) is described. Advantages and disadvantages of different nitration reagents which involve acidic conditions (HNO3/H+) and neutral conditions (Cu(NO3)2; ceric ammonium nitrate) are discussed. A complete 1H and 13C-nmr characterization including ms and also uv absorption spectra in neutral and acid media is presented. A detailed ei-ms and ld-tof-ms study is enclosed because the nitro-β-carbolines constitute a new family of β-carboline-like chromophores with potential use as matrix in uv-maldi-tof-ms.

A new method of nitration of carbazoles using ceric ammonium nitrate (CAN)

Chakrabarty,Batabyal

, p. 1 - 10 (2007/10/02)

A convenient procedure for the mononitration of carbazole and 9-alkylcarbazoles using CAN in CH3CN in presence of SiO2 is reported. The results with 9-acetyl, 9-benzoyl and 9- benzenesulphonylcarbazoles are also discussed.
