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.
(3AR,4s,9bs)-6,9-dimethyl-3a,4,5,9b-tetrahydro-3h-cyclopenta[c]quinoline-4-carboxylic acid (CAS 1415811-56-1), molecular formula C15H17NO2 and molecular weight 243.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (3AR,4s,9bs)-6,9-dimethyl-3a,4,5,9b-tetrahydro-3h-cyclopenta[c]quinoline-4-carboxylic acid (C15H17NO2) is characterized by a nitrogen-containing heterocyclic scaffold, 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
