Chemical Structure
Description
The occurrence of rel-(2R,3R)-3-(Ethoxycarbonyl)oxirane-2-carboxylic acid is closely related to a carbohydrate-derived structure in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies rel-(2R,3R)-3-(Ethoxycarbonyl)oxirane-2-carboxylic acid (CAS 63734-73-6), a certified reference material (molecular formula C6H7O5, MW 159.12 g/mol) for analytical method development and quality control.
Owing to a carbohydrate-derived structure, rel-(2R,3R)-3-(Ethoxycarbonyl)oxirane-2-carboxylic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 159.12 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
