Chemical Structure
Description
The occurrence of 1-Oxo-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Oxo-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid (CAS 63586-82-3) is a high-purity analytical reference standard with the molecular formula C10H9NO3 and a molecular weight of 191.18 g/mol.
1-Oxo-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid (C10H9NO3) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
