6972-76-5 Usage

General Description

Dinitrosodimethylpropanediamine, also known as Methylene bisthiocyanate, is a chemical compound commonly used as a rubber additive and biocide. It is a yellow powder with a strong, pungent odor and is considered to be a potential occupational hazard due to its toxicity and potential to cause skin and eye irritation. It is typically used as a preservative in industrial water systems, and in the production of rubber, but it is also used in some consumer products, such as adhesives and sealants. Due to its potential health and environmental risks, the use and handling of dinitrosodimethylpropanediamine is subject to strict regulations and safety precautions.

Check Digit Verification of cas no

The CAS Registry Mumber 6972-76-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,7 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6972-76:
(6*6)+(5*9)+(4*7)+(3*2)+(2*7)+(1*6)=135
135 % 10 = 5
So 6972-76-5 is a valid CAS Registry Number.

Nitrolysis of Tertiary Amines: Piperidines, Piperazines, Bisdimethylaminoalkanes, and Functionalized Methyldialkylamines

Boyer, Joseph H.,Kumar, Govindarajulu,Pillai, T. Perumal

, p. 1751 - 1754 (2007/10/02)

Preparative amounts of mono- and di-nitrosamines were obtained from aliphatic cyclic and acyclic tertiary monamines and diamines by treatment with dinitrogen tetraoxide in carbon tetrachloride at 0 - 45 deg C.N-Methyl- and N-ethyl-piperidines (1) and (2) gave N-nitrosopiperidine (15), but N-isopropyl- and N-t-butyl-piperidines (3) and (4) did not.N-Methyl-, N-ethyl-, N-isopropyl- and N-t-butyl-N'-methylpiperazines (5) - (8) gave N,N'-dinitrosopiperazine (22) (in 90 percent, 81 percent, 55 percent, and 8 percent yields, respectively) and the diamine (8) also gave N-t-butyl-N'-dinitrosopiperazine (23) (45 percent).The N'-nitroso and the N'-nitro derivatives of N-methylpiperazine were similarly converted into N,N'-dinitroso- and N-nitroso-N'-nitropiperazines (22) (45 percent) and (30) (53 percent).Bisdimethylaminoalkanes (Me2N)2(CH2)n (10) - (14) gave bismethylnitrosaminoalkanes 2(CH2)n (24) - (27) and dimethylnitrosamine (28): n=1 (0 percent, 90 percent); n=2 (68 percent, 0 percent); n=3 (48 percent, 43 percent); n=4 (41 percent, 38 percent); n=6 (58 percent, 35 percent). β-Dimethylaminopropionitrile (18), 1-methylnitrosamino-2-dimethylaminoethane (17), and α-dimethylaminoacetic acid (19) gave the corresponding nitrosoamines by replacement of an N-methyl group.
