99191-71-6 Usage
General Description
HEXANE-1,6-DIYLBIS(METHYLCARBAMIC CHLORIDE) is a chemical compound used in the production of pesticides and pharmaceuticals. It is a derivative of hexane, a common solvent in industry, and is synthesized by reacting hexane-1,6-diamine with methyl isocyanate and phosgene. The resulting compound is a chloroformate that is used as an intermediate in the manufacture of carbamate insecticides such as aldicarb and carbofuran. HEXANE-1,6-DIYLBIS(METHYLCARBAMIC CHLORIDE) is also used in the production of certain pharmaceuticals, particularly as a potential cross-linking agent in drug delivery systems. However, it is important to handle this compound with care, as it is classified as toxic and potentially harmful to human health and the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 99191-71-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,1,9 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 99191-71:
(7*9)+(6*9)+(5*1)+(4*9)+(3*1)+(2*7)+(1*1)=176
176 % 10 = 6
So 99191-71-6 is a valid CAS Registry Number.

Preparation method of high-purity distigmine bromide
-
Paragraph 0007; 0021-0023, (2018/04/28)
The invention relates to a preparation method of high-purity distigmine bromide and aims to provide a method being economical, environmentally friendly, convenient to operate and suitable for large-scale industrial production for synthesizing high-purity and high-yield distigmine bromide. In the synthesis method, the volume ratio of acetonitrile to acetone for refining distigmine bromide is (20-50): 1, preferably (25-30): 1.
