21483-63-6 Usage
General Description
1,1,1,2,3,4,4-heptachloro-2-butene is a synthetic chemical compound used as a pesticide and industrial chemical. It is a colorless liquid that is highly volatile and prone to forming toxic fumes when exposed to heat or flame. This chemical is classified as a possible human carcinogen and has been linked to adverse health effects such as liver damage, nervous system disorders, and reproductive issues in animal studies. Due to its toxicity and environmental persistence, its use has been restricted and phased out in many countries. However, it is still found as a contaminant in soil, water, and some products, posing a risk to human health and the environment. Strict regulations and proper disposal measures are necessary to minimize exposure to this hazardous chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 21483-63-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,4,8 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21483-63:
(7*2)+(6*1)+(5*4)+(4*8)+(3*3)+(2*6)+(1*3)=96
96 % 10 = 6
So 21483-63-6 is a valid CAS Registry Number.

SYNTHESIS OF POLYFUNCTIONAL ORGANOCHLORINE COMPOUNDS BASED ON 1,1,1,2,3,3,4,4-OCTACHLOROBUTANE

2,3,3,4,4-Pentachlorobutyric acid was obtained with a preparative yield by the reaction of 1,1,1,2,3,3,4,4-octachlorobutane with oleum.The dehydrochlorination of octachlorobutane with an equimolar amount of an aqueous solution of sodium hydroxide, catalyzed by triethylbenzylammonium chloride, takes place by the elimination of one molecule of hydrogen chloride from positions 1,2 and 2,3 with the formation of isomeric heptachlorobutenes.Hydrolysis of the latter with fuming nitric acid gave the difficultly obtainable 1,1,2,4,4-pentachloro-1-buten-3-one and Z-α,β,χ,χ-tetrachlorocrotonic acid.
