Chemical Structure
Description
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.
6-Chloronaphthalene-2-sulfonyl chloride, 97% (CAS 102153-63-9) is a high-purity analytical reference standard with the molecular formula C10H6Cl2O2S and a molecular weight of 261.12 g/mol.
The molecular framework of 6-Chloronaphthalene-2-sulfonyl chloride, 97% (C10H6Cl2O2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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).
CATO manufactures 6-Chloronaphthalene-2-sulfonyl chloride, 97% 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.
