8-Methoxy-3a,4,5,9b-tetrahydro-3H-cyclopenta[c]quinoline-4-carboxylic acid CAS 247225-89-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 245.27 g/mol gives 8-Methoxy-3a,4,5,9b-tetrahydro-3H-cyclopenta[c]quinoline-4-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 8-Methoxy-3a,4,5,9b-tetrahydro-3H-cyclopenta[c]quinoline-4-carboxylic acid (CAS 247225-89-4), a certified reference material (molecular formula C14H15NO3, MW 245.27 g/mol) for analytical method development and quality control.

8-Methoxy-3a,4,5,9b-tetrahydro-3H-cyclopenta[c]quinoline-4-carboxylic acid (C14H15NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), 8-Methoxy-3a,4,5,9b-tetrahydro-3H-cyclopenta[c]quinoline-4-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
