Chemical Structure

(S)-Methyl 4-methyl-4,5-dihydrooxazole-4-carboxylate CAS 117176-06-4 chemical structure

Description

The occurrence of (S)-Methyl 4-methyl-4,5-dihydrooxazole-4-carboxylate is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(S)-Methyl 4-methyl-4,5-dihydrooxazole-4-carboxylate (CAS 117176-06-4), molecular formula C6H9NO3 and molecular weight 143.14 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (S)-Methyl 4-methyl-4,5-dihydrooxazole-4-carboxylate (C6H9NO3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures (S)-Methyl 4-methyl-4,5-dihydrooxazole-4-carboxylate 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.
