Chemical Structure
Description
Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 2-({5-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]pyrimidin-2-yl}sulfanyl)-1-(4-chlorophenyl)ethan-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 444.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO supplies 2-({5-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]pyrimidin-2-yl}sulfanyl)-1-(4-chlorophenyl)ethan-1-one (CAS 344263-13-4), a certified reference material (molecular formula C18H10Cl2F3N3OS, MW 444.26 g/mol) for analytical method development and quality control.
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.
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.
