Chemical Structure
Description
Owing to a steroid core, a hydroxyl group, an ether linkage, 3-(4-Methoxyphenyl)-1-(p-tolyl)prop-2-yn-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 250.29 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 3-(4-Methoxyphenyl)-1-(p-tolyl)prop-2-yn-1-one (CAS 65418-75-9), a certified reference material (molecular formula C17H14O2, MW 250.29 g/mol) for analytical method development and quality control.
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.
