Chemical Structure
Description
Structurally, (3AR,4s,9bs)-8-bromo-3a,4,5,9b-tetrahydro-3h-cyclopenta[c]quinoline-4-carboxylic acid (C13H12BrNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine 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 294.14 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.
(3AR,4s,9bs)-8-bromo-3a,4,5,9b-tetrahydro-3h-cyclopenta[c]quinoline-4-carboxylic acid (CAS 1415811-75-4), molecular formula C13H12BrNO2 and molecular weight 294.14 g/mol, is a CATO reference standard with documented purity and traceability.
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.
