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.
3-(3,4-Dimethoxyphenyl)-6-(pentafluoro-λ6-sulfanyl)benzo[c]isoxazole (CAS 1379812-02-8) is a high-purity analytical reference standard with the molecular formula C15H12F5NO3S and a molecular weight of 381.32 g/mol.
The molecular framework of 3-(3,4-Dimethoxyphenyl)-6-(pentafluoro-λ6-sulfanyl)benzo[c]isoxazole (C15H12F5NO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. 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 3-(3,4-Dimethoxyphenyl)-6-(pentafluoro-λ6-sulfanyl)benzo[c]isoxazole 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.
