Chemical Structure
Description
CATO supplies 5-(1,2-Dihydro-[1,1':4',1''-terphenyl]-2-yl)-3H-1,2,4-triazol-3-one (CAS 1000575-71-2), a certified reference material (molecular formula C20H15N3O, MW 313.35 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 5-(1,2-Dihydro-[1,1':4',1''-terphenyl]-2-yl)-3H-1,2,4-triazol-3-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 313.35 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).
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.
