Chemical Structure
Description
Hex-5-yn-1-yl 4-methylbenzenesulfonate (CAS 76911-01-8), molecular formula C13H16O3S and molecular weight 252.33 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Hex-5-yn-1-yl 4-methylbenzenesulfonate (C13H16O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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).
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 Hex-5-yn-1-yl 4-methylbenzenesulfonate 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.
