Chemical Structure
Description
The occurrence of 1-{5-[4-(Benzyloxy)phenyl]-2-thienyl}ethanone is closely related to a steroid core, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-{5-[4-(Benzyloxy)phenyl]-2-thienyl}ethanone (CAS 893739-20-3), a certified reference material (molecular formula C19H16O2S, MW 308.39 g/mol) for analytical method development and quality control.
The molecular framework of 1-{5-[4-(Benzyloxy)phenyl]-2-thienyl}ethanone (C19H16O2S) 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
