Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(Hydroxymethyl)oxazole-4-carboxylic acid.
CATO supplies 2-(Hydroxymethyl)oxazole-4-carboxylic acid (CAS 1240607-91-3), a certified reference material (molecular formula C5H5NO4, MW 143.10 g/mol) for analytical method development and quality control.
Structurally, 2-(Hydroxymethyl)oxazole-4-carboxylic acid (C5H5NO4) contains a carbohydrate-derived structure, an amide group. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 143.10 g/mol, it falls into the low-molecular-weight range. 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.
CATO manufactures 2-(Hydroxymethyl)oxazole-4-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
