Chemical Structure

Rel-(2R,3R)-3-(methoxycarbonyl)oxirane-2-carboxylic acid CAS 119240-65-2 chemical structure

Description

As a certified reference material (CRM), Rel-(2R,3R)-3-(methoxycarbonyl)oxirane-2-carboxylic acid 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 Rel-(2R,3R)-3-(methoxycarbonyl)oxirane-2-carboxylic acid (CAS 119240-65-2), a certified reference material (molecular formula C5H6O5, MW 146.10 g/mol) for analytical method development and quality control.

Owing to a carbohydrate-derived structure, Rel-(2R,3R)-3-(methoxycarbonyl)oxirane-2-carboxylic acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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