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.
CATO supplies (2E)-1-{[1,1'-Biphenyl]-4-yl}-3-(5-methylthiophen-2-yl)prop-2-en-1-one (CAS 1003448-23-4), a certified reference material (molecular formula C20H16OS, MW 304.41 g/mol) for analytical method development and quality control.
Owing to a steroid core, sulfur-containing functionality, a hydroxyl group, an ether linkage, (2E)-1-{[1,1'-Biphenyl]-4-yl}-3-(5-methylthiophen-2-yl)prop-2-en-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
