Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-[(3AR,4s,9bs)-6,8-dichloro-3a,4,5,9b-tetrahydro-3h-cyclopenta[c]quinolin-4-yl]benzoic acid.
4-[(3AR,4s,9bs)-6,8-dichloro-3a,4,5,9b-tetrahydro-3h-cyclopenta[c]quinolin-4-yl]benzoic acid (CAS 955964-05-3) is a high-purity analytical reference standard with the molecular formula C19H15Cl2NO2 and a molecular weight of 360.23 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 4-[(3AR,4s,9bs)-6,8-dichloro-3a,4,5,9b-tetrahydro-3h-cyclopenta[c]quinolin-4-yl]benzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 360.23 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.
