2-Acetoxypropionyl Chloride CAS 38939-83-2 chemical structure

Description

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

2-Acetoxypropionyl Chloride (CAS 38939-83-2), molecular formula C5H7ClO3 and molecular weight 150.56 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 2-Acetoxypropionyl Chloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 150.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

As a certified reference material (CRM), 2-Acetoxypropionyl Chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
