Chemical Structure
Description
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.
(4AS,4bR,8S,10aR,10bS,12aS)-10a,12a-dimethyl-1,2,3,4,4a,4b,5,7,8,9,10,10a,10b,11,12,12a-hexadecahydronaphtho[2,1-f]quinolin-8-ol (CAS 6961-52-0), molecular formula C19H31NO and molecular weight 289.46 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4AS,4bR,8S,10aR,10bS,12aS)-10a,12a-dimethyl-1,2,3,4,4a,4b,5,7,8,9,10,10a,10b,11,12,12a-hexadecahydronaphtho[2,1-f]quinolin-8-ol (C19H31NO) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
