Chemical Structure

Ethyl 2-(chlorocarbonyl)butanoate CAS 37938-52-6 chemical structure

Description

As a certified reference material (CRM), Ethyl 2-(chlorocarbonyl)butanoate 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.

CATO supplies Ethyl 2-(chlorocarbonyl)butanoate (CAS 37938-52-6), a certified reference material (molecular formula C7H11ClO3, MW 178.61 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Ethyl 2-(chlorocarbonyl)butanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 178.61 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.

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