6-Methoxy-1,2,3,4-tetrahydro-quinoline-2-carboxylic acid methyl ester hydrochloride CAS 176641-34-2 chemical structure

Description

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.

6-Methoxy-1,2,3,4-tetrahydro-quinoline-2-carboxylic acid methyl ester hydrochloride (CAS 176641-34-2) is a high-purity analytical reference standard with the molecular formula C12H15NO3HCl and a molecular weight of 257.71 g/mol.

6-Methoxy-1,2,3,4-tetrahydro-quinoline-2-carboxylic acid methyl ester hydrochloride (C12H15NO3HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.

As a certified reference material (CRM), 6-Methoxy-1,2,3,4-tetrahydro-quinoline-2-carboxylic acid methyl ester hydrochloride 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.
