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 3-(5-Hydroxy-1,2,4-oxadiazol-3-yl)benzoic acid.
CATO supplies 3-(5-Hydroxy-1,2,4-oxadiazol-3-yl)benzoic acid (CAS 1206894-79-2), a certified reference material (molecular formula C9H6N2O4, MW 206.15 g/mol) for analytical method development and quality control.
3-(5-Hydroxy-1,2,4-oxadiazol-3-yl)benzoic acid (C9H6N2O4) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 3-(5-Hydroxy-1,2,4-oxadiazol-3-yl)benzoic 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.
