Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (2E)-1-(2,4-Dimethylphenyl)-3-(4-methylphenyl)prop-2-en-1-one (CAS 200934-19-6), a certified reference material (molecular formula C18H18O, MW 250.33 g/mol) for analytical method development and quality control.
Owing to a steroid core, a hydroxyl group, an ether linkage, (2E)-1-(2,4-Dimethylphenyl)-3-(4-methylphenyl)prop-2-en-1-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 250.33 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.
