7-Chloro-6-methyl-1,3,4,5-tetrahydrobenzo[b][1,6]naphthyridin-10(2H)-one CAS 1338658-76-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-Chloro-6-methyl-1,3,4,5-tetrahydrobenzo[b][1,6]naphthyridin-10(2H)-one.

CATO supplies 7-Chloro-6-methyl-1,3,4,5-tetrahydrobenzo[b][1,6]naphthyridin-10(2H)-one (CAS 1338658-76-6), a certified reference material (molecular formula C13H13ClN2O, MW 248.71 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 7-Chloro-6-methyl-1,3,4,5-tetrahydrobenzo[b][1,6]naphthyridin-10(2H)-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 248.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
