5-Chloro-2-[4-(chloromethyl)phenyl]-1,3-benzothiazole CAS 1096267-76-3

Description

The occurrence of 5-Chloro-2-[4-(chloromethyl)phenyl]-1,3-benzothiazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Chloro-2-[4-(chloromethyl)phenyl]-1,3-benzothiazole (CAS 1096267-76-3), molecular formula C14H9Cl2NS and molecular weight 294.20 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Chloro-2-[4-(chloromethyl)phenyl]-1,3-benzothiazole (C14H9Cl2NS) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
