Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Ethyl-2-methyl-N-(6-methylpyridin-2-yl)-4-oxo-1,4-dihydroquinoline-6-carboxamide.
CATO supplies 1-Ethyl-2-methyl-N-(6-methylpyridin-2-yl)-4-oxo-1,4-dihydroquinoline-6-carboxamide (CAS 1018130-27-2), a certified reference material (molecular formula C19H19N3O2, MW 321.37 g/mol) for analytical method development and quality control.
Structurally, 1-Ethyl-2-methyl-N-(6-methylpyridin-2-yl)-4-oxo-1,4-dihydroquinoline-6-carboxamide (C19H19N3O2) 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 321.37 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
