Chemical Structure

3,4-Dihydro-1H-pyrido[3,4-b]indole-5,6(2H,9H)-dione CAS 150254-83-4 chemical structure

Description

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.

CATO supplies 3,4-Dihydro-1H-pyrido[3,4-b]indole-5,6(2H,9H)-dione (CAS 150254-83-4), a certified reference material (molecular formula C11H10N2O2, MW 202.21 g/mol) for analytical method development and quality control.

3,4-Dihydro-1H-pyrido[3,4-b]indole-5,6(2H,9H)-dione (C11H10N2O2) 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 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.
