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 4-((4-(3-Chlorophenyl)piperazin-1-yl)methyl)-6-ethyl-2H-chromen-2-one hydrochloride (CAS 1177436-90-6), a certified reference material (molecular formula C22H23ClN2O2HCl, MW 419.35 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 4-((4-(3-Chlorophenyl)piperazin-1-yl)methyl)-6-ethyl-2H-chromen-2-one hydrochloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 419.35 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.
