Compared with other compounds in its class, the molecular weight of 284.14 g/mol gives (3AR,4s,9bs)-6,8-dichloro-3a,4,5,9b-tetrahydro-3h-cyclopenta[c]quinoline-4-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(3AR,4s,9bs)-6,8-dichloro-3a,4,5,9b-tetrahydro-3h-cyclopenta[c]quinoline-4-carboxylic acid (CAS 1415811-53-8) is a high-purity analytical reference standard with the molecular formula C13H11Cl2NO2 and a molecular weight of 284.14 g/mol.
Structurally, (3AR,4s,9bs)-6,8-dichloro-3a,4,5,9b-tetrahydro-3h-cyclopenta[c]quinoline-4-carboxylic acid (C13H11Cl2NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 284.14 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
