Chemical Structure

Ethyl 2-sulfopentanoate CAS 1556927-66-2 chemical structure

Description

The occurrence of Ethyl 2-sulfopentanoate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Ethyl 2-sulfopentanoate (CAS 1556927-66-2), a certified reference material (molecular formula C7H13ClO4S, MW 228.69 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Ethyl 2-sulfopentanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 228.69 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.

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