Chemical Structure

2-[[5-(4-Chlorophenyl)-1,3,4-oxadiazol-2-yl]thio]acetic Acid CAS 49809-28-1 chemical structure

Description

The occurrence of 2-[[5-(4-Chlorophenyl)-1,3,4-oxadiazol-2-yl]thio]acetic Acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-[[5-(4-Chlorophenyl)-1,3,4-oxadiazol-2-yl]thio]acetic Acid (CAS 49809-28-1), a certified reference material (molecular formula C10H7ClN2O3S, MW 270.69 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, chlorine substitution, 2-[[5-(4-Chlorophenyl)-1,3,4-oxadiazol-2-yl]thio]acetic Acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 270.69 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 2-[[5-(4-Chlorophenyl)-1,3,4-oxadiazol-2-yl]thio]acetic 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.
