The occurrence of 2-(1,3,4-Trioxo-3,4-dihydroisoquinolin-2(1H)-yl)acetic 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.

2-(1,3,4-Trioxo-3,4-dihydroisoquinolin-2(1H)-yl)acetic acid (CAS 161426-90-0), molecular formula C11H7NO5 and molecular weight 233.18 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-(1,3,4-Trioxo-3,4-dihydroisoquinolin-2(1H)-yl)acetic acid (C11H7NO5) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 233.18 g/mol, it falls into the medium-molecular-weight range. 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.
