Product name Chloropivaloyl chloride Alias 3-Chloro-2,2-Dimethyl Propionyl Chloride;3-Chloro-2,2-dimethylpropionyl chloride Appearance Colorless transparent irritative liquid Cas 4300-97-4 Einecs 224-311-8 Hazard sign 8 UN number 1760 Assay 99% Package 250kg/drum Boiling point 85-86°C (60mmHg) flash point 62°C density 1.99 refractive index 1.452-1.454 2.applicaton: Acid chlorides are used as very reactive intermediates to prepare carboxylic acid derivatives including anhydrides, esters and amides because of the two strong electron withdrawing chlorine and oxygen on the carbonyl compound, and positive charge carbon accordingly. It is easy for a weak nucleophile to attack the carbon. Acid chlorides are also reactive with Gilman reagents to prepare large molecules from small ones by replacing the halides with an organic group. 3-Chloropivaloyl chloride, , multi-methylated acetyl chloride with an additional chloride at the terminal carbon, is used as an intermediate for the manufacturing photographic developers, herbicides, pesticides and rubber additives. It is used as an initiator of chain reaction for vinyl chloride-propylene copolymers.
