Description

CATO supplies N-(1-benzyl-3-methyl-2-oxo-1,2-dihydroquinoxalin-6-yl)acetamide (CAS 1243075-52-6), a certified reference material (molecular formula C18H17N3O2, MW 307.35 g/mol) for analytical method development and quality control.

Structurally, N-(1-benzyl-3-methyl-2-oxo-1,2-dihydroquinoxalin-6-yl)acetamide (C18H17N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 307.35 g/mol, it falls into the moderately-high-molecular-weight range. 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.
