6H,7H,8H,9H,10H-Cyclohepta[b]quinoline-11-carboxylic acid CAS 7101-63-5

Description

The occurrence of 6H,7H,8H,9H,10H-Cyclohepta[b]quinoline-11-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6H,7H,8H,9H,10H-Cyclohepta[b]quinoline-11-carboxylic acid (CAS 7101-63-5), molecular formula C15H15NO2 and molecular weight 241.29 g/mol, is a CATO reference standard with documented purity and traceability.

6H,7H,8H,9H,10H-Cyclohepta[b]quinoline-11-carboxylic acid (C15H15NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.

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.
