7-Methyl-9-oxo-9,11-dihydroindolizino[1,2-b]quinoline-8-carbonitrile CAS 66917-21-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-Methyl-9-oxo-9,11-dihydroindolizino[1,2-b]quinoline-8-carbonitrile.

CATO supplies 7-Methyl-9-oxo-9,11-dihydroindolizino[1,2-b]quinoline-8-carbonitrile (CAS 66917-21-3), a certified reference material (molecular formula C17H11N3O, MW 273.29 g/mol) for analytical method development and quality control.

Structurally, 7-Methyl-9-oxo-9,11-dihydroindolizino[1,2-b]quinoline-8-carbonitrile (C17H11N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 273.29 g/mol, it falls into the medium-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.
