Chemical Structure
Description
3-[3-(1,3-dioxolan-2-yl)-2-thienyl]-1-[3-(trifluoromethyl)phenyl]prop-2-en-1-one (CAS 256353-55-6) is a high-purity analytical reference standard with the molecular formula C17H13F3O3S and a molecular weight of 354.34 g/mol.
The molecular framework of 3-[3-(1,3-dioxolan-2-yl)-2-thienyl]-1-[3-(trifluoromethyl)phenyl]prop-2-en-1-one (C17H13F3O3S) is characterized by a steroid core, 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).
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.
CATO manufactures 3-[3-(1,3-dioxolan-2-yl)-2-thienyl]-1-[3-(trifluoromethyl)phenyl]prop-2-en-1-one 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.
