3-Chloroisothiazole CAS 14217-66-4 chemical structure

Description

CATO manufactures 3-Chloroisothiazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

3-Chloroisothiazole (CAS 14217-66-4), molecular formula C3H2ClNS and molecular weight 119.57 g/mol, is a CATO reference standard with documented purity and traceability.

3-Chloroisothiazole (C3H2ClNS) contains a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
