Chemical Structure

methyl 1,2,5-oxadiazole-3-carboxylate CAS 148122-20-7 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 methyl 1,2,5-oxadiazole-3-carboxylate.

methyl 1,2,5-oxadiazole-3-carboxylate (CAS 148122-20-7) is a high-purity analytical reference standard with the molecular formula C4H8N2O3 and a molecular weight of 132.12 g/mol.

methyl 1,2,5-oxadiazole-3-carboxylate (C4H8N2O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 methyl 1,2,5-oxadiazole-3-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.
