2-[5-methyl-2-(thiophen-3-yl)-1,3-oxazol-4-yl]acetic acid CAS 1240529-53-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-[5-methyl-2-(thiophen-3-yl)-1,3-oxazol-4-yl]acetic acid.

CATO supplies 2-[5-methyl-2-(thiophen-3-yl)-1,3-oxazol-4-yl]acetic acid (CAS 1240529-53-6), a certified reference material (molecular formula C10H9NO3S, MW 223.25 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-[5-methyl-2-(thiophen-3-yl)-1,3-oxazol-4-yl]acetic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 223.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 2-[5-methyl-2-(thiophen-3-yl)-1,3-oxazol-4-yl]acetic 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.
