628-20-6 Usage
Chemical Properties
Clear Colourless Liquid
Uses
4-Chlorobutyronitrile (cas# 628-20-6) is a compound useful in organic synthesis.
General Description
A liquid. Flash point 85°F. Density about 9.7 lb / gal and practically insoluble in water (2 parts/100 parts water). Hence sinks in water. Vapors are heavier than air. Irritates the eyes but not to the skin. Releases hydrogen chloride, hydrogen cyanide, and hydrogen bromide gases when heated or involved in a fire.
Air & Water Reactions
Highly flammable. Practically insoluble in water.
Reactivity Profile
4-Chlorobutyronitrile may attack some forms of plastics [USCG, 1999].
Health Hazard
Chemical is moderately toxic. Inhalation causes irritation of nose and throat. Ingestion causes irritation of mouth and stomach. Contact with eyes causes irritation. Can penetrate the skin on prolonged contact; only slightly irritating.
Fire Hazard
Special Hazards of Combustion Products: Toxic and irritating hydrogen cyanide, hydrogen bromide, and hydrogen chloride may form in fires.
Check Digit Verification of cas no
The CAS Registry Mumber 628-20-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 628-20:
(5*6)+(4*2)+(3*8)+(2*2)+(1*0)=66
66 % 10 = 6
So 628-20-6 is a valid CAS Registry Number.
