5-(2-(Methylthio)ethyl)-1,2,4-oxadiazole-3-carboxylic acid CAS 1343032-47-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(2-(Methylthio)ethyl)-1,2,4-oxadiazole-3-carboxylic acid.

5-(2-(Methylthio)ethyl)-1,2,4-oxadiazole-3-carboxylic acid (CAS 1343032-47-2), molecular formula C6H8N2O3S and molecular weight 188.20 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-(2-(Methylthio)ethyl)-1,2,4-oxadiazole-3-carboxylic acid (C6H8N2O3S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.

As a certified reference material (CRM), 5-(2-(Methylthio)ethyl)-1,2,4-oxadiazole-3-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
