CATO supplies 2-Oxo-2,3-dihydro-1H-pyrrolo[2,3-b]pyridine-4-carboxylic acid (CAS 1190310-95-2), a certified reference material (molecular formula C8H6N2O3, MW 178.14 g/mol) for analytical method development and quality control.
2-Oxo-2,3-dihydro-1H-pyrrolo[2,3-b]pyridine-4-carboxylic acid (C8H6N2O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
