Chemical Structure

2-(Chloromethyl)-3-methylbenzo[d]thiazol-3-ium 4-methylbenzenesulfonate CAS 37859-49-7 chemical structure

Description

The occurrence of 2-(Chloromethyl)-3-methylbenzo[d]thiazol-3-ium 4-methylbenzenesulfonate 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.

2-(Chloromethyl)-3-methylbenzo[d]thiazol-3-ium 4-methylbenzenesulfonate (CAS 37859-49-7), molecular formula C9H9ClNSC7H7O3S and molecular weight 369.88 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(Chloromethyl)-3-methylbenzo[d]thiazol-3-ium 4-methylbenzenesulfonate (C9H9ClNSC7H7O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, 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. 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-(Chloromethyl)-3-methylbenzo[d]thiazol-3-ium 4-methylbenzenesulfonate 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.
