Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4AR,4bS,6aS,7S,9aS,9bS,11aR)-7-(hydroxymethyl)-4a,6a-dimethyl-1,4a,4b,5,6,6a,7,8,9,9a,9b,10,11,11a-tetradecahydro-2H-indeno[5,4-f]quinolin-2-one.

(4AR,4bS,6aS,7S,9aS,9bS,11aR)-7-(hydroxymethyl)-4a,6a-dimethyl-1,4a,4b,5,6,6a,7,8,9,9a,9b,10,11,11a-tetradecahydro-2H-indeno[5,4-f]quinolin-2-one (CAS 139230-03-8) is a high-purity analytical reference standard with the molecular formula C19H29NO2 and a molecular weight of 303.44 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (4AR,4bS,6aS,7S,9aS,9bS,11aR)-7-(hydroxymethyl)-4a,6a-dimethyl-1,4a,4b,5,6,6a,7,8,9,9a,9b,10,11,11a-tetradecahydro-2H-indeno[5,4-f]quinolin-2-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 303.44 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.
