2-acetoxyisobutyryl chloride 40635-66-3 1-CHLORO-2-METHYL-1-OXOPROPAN-2-YL ACETATE;1-CHLOROCARBONYL-1-METHYLETHYL ACETATE;2-ACETOXY-2-METHYLPROPIONYL CHLORIDE;2-ACETOXYISOBUTYRYL CHLORIDE;ACETOXY-ISO-BUTYRYLCHLORIDE;ALPHA-ACETOXY-ISOBUTYRYL CHLORIDE;CHLOROCARBONYL-1-METHYLETHYL ACETATE JC10158 (C6H9ClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
