Description

Compared with other compounds in its class, the molecular weight of 294.18 g/mol gives 2-Chloro-4-phenylthiazole-5-sulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Chloro-4-phenylthiazole-5-sulfonyl chloride (CAS 2138159-10-9), molecular formula C9H5Cl2NO2S2 and molecular weight 294.18 g/mol, is a CATO reference standard with documented purity and traceability.

2-Chloro-4-phenylthiazole-5-sulfonyl chloride (C9H5Cl2NO2S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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).

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), 2-Chloro-4-phenylthiazole-5-sulfonyl chloride 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.
