Description

Compared with other compounds in its class, the molecular weight of 211.67 g/mol gives 5-(4-Chlorophenyl)-1,3-oxazole-2-thiol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-(4-Chlorophenyl)-1,3-oxazole-2-thiol (CAS 49656-34-0), molecular formula C9H6ClNOS and molecular weight 211.67 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-(4-Chlorophenyl)-1,3-oxazole-2-thiol (C9H6ClNOS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 5-(4-Chlorophenyl)-1,3-oxazole-2-thiol 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.
