Description
CATO manufactures 2,3-Dinonylnaphthalene-1-sulfonic acid 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.
CATO supplies 2,3-Dinonylnaphthalene-1-sulfonic acid (CAS 25322-17-2), a certified reference material (molecular formula C28H44O3S, MW 460.71 g/mol) for analytical method development and quality control.
The molecular framework of 2,3-Dinonylnaphthalene-1-sulfonic acid (C28H44O3S) is characterized by a steroid core, a sulfone group, a hydroxyl group, an ether linkage. 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.
