Chemical Structure
Description
The molecular framework of 4-(Pentyloxy)benzenesulfonyl chloride (C11H15ClO3S) 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).
4-(Pentyloxy)benzenesulfonyl chloride (CAS 58076-33-8) is a high-purity analytical reference standard with the molecular formula C11H15ClO3S and a molecular weight of 262.75 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4-(Pentyloxy)benzenesulfonyl 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.
