Chemical Structure
Description
6-Methoxy-1,2,3,4-tetrahydroisoquinoline-1-carboxylic acid (C11H13NO3) contains an amino-acid-derived structure, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
6-Methoxy-1,2,3,4-tetrahydroisoquinoline-1-carboxylic acid (CAS 1161833-78-8), molecular formula C11H13NO3 and molecular weight 207.23 g/mol, is a CATO reference standard with documented purity and traceability.
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.
