5-Acetylisoquinolin-1(2H)-one CAS 1420790-63-1

Description

The occurrence of 5-Acetylisoquinolin-1(2H)-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.

5-Acetylisoquinolin-1(2H)-one (CAS 1420790-63-1), molecular formula C11H9NO2 and molecular weight 187.19 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H9NO2, 5-Acetylisoquinolin-1(2H)-one contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 187.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
