Chemical Structure
Description
CATO supplies 1-(4-Hydroxy-3,5-dimethylphenyl)-2-((4-methoxyphenyl)sulfonyl)ethan-1-one (CAS 339100-53-7), a certified reference material (molecular formula C17H18O5S, MW 334.39 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, 1-(4-Hydroxy-3,5-dimethylphenyl)-2-((4-methoxyphenyl)sulfonyl)ethan-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 334.39 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).
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.
