The occurrence of 3-Amino-4-hydroxy-1-methylquinolin-2(1H)-one 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.
3-Amino-4-hydroxy-1-methylquinolin-2(1H)-one (CAS 70744-03-5), molecular formula C10H10N2O2 and molecular weight 190.20 g/mol, is a CATO reference standard with documented purity and traceability.
3-Amino-4-hydroxy-1-methylquinolin-2(1H)-one (C10H10N2O2) 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 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.
CATO manufactures 3-Amino-4-hydroxy-1-methylquinolin-2(1H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
