3-(3-Ethyl-1,2,4-oxadiazol-5-yl)benzoic acid CAS 902837-22-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(3-Ethyl-1,2,4-oxadiazol-5-yl)benzoic acid.

CATO supplies 3-(3-Ethyl-1,2,4-oxadiazol-5-yl)benzoic acid (CAS 902837-22-3), a certified reference material (molecular formula C11H10N2O3, MW 218.21 g/mol) for analytical method development and quality control.

The molecular framework of 3-(3-Ethyl-1,2,4-oxadiazol-5-yl)benzoic acid (C11H10N2O3) 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. 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 3-(3-Ethyl-1,2,4-oxadiazol-5-yl)benzoic 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.
