Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
7-Chloro-3-(piperazin-1-yl)benzo[d]isothiazole (CAS 1329835-54-2) is a high-purity analytical reference standard with the molecular formula C11H12ClN3S and a molecular weight of 253.75 g/mol.
The molecular framework of 7-Chloro-3-(piperazin-1-yl)benzo[d]isothiazole (C11H12ClN3S) 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.
CATO manufactures 7-Chloro-3-(piperazin-1-yl)benzo[d]isothiazole 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.
