Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N-(Benzo[d]thiazol-5-yl)-5-chlorothiophene-2-carboxamide (CAS 941966-27-4), molecular formula C12H7ClN2OS2 and molecular weight 294.78 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(Benzo[d]thiazol-5-yl)-5-chlorothiophene-2-carboxamide (C12H7ClN2OS2) 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 its high hydrophobicity (logP), 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.
As a certified reference material (CRM), N-(Benzo[d]thiazol-5-yl)-5-chlorothiophene-2-carboxamide 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.
