Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
6-Chloro-2,3-dihydro-1H-indene-5-sulfonyl chloride (CAS 1541069-38-8), molecular formula C9H8Cl2O2S and molecular weight 251.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-Chloro-2,3-dihydro-1H-indene-5-sulfonyl chloride (C9H8Cl2O2S) 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 the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 6-Chloro-2,3-dihydro-1H-indene-5-sulfonyl chloride 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.
