Ethyl 3-methyl-4-oxo-4,5,6,7-tetrahydro-2H-isoindole-1-carboxylate CAS 65038-91-7

Description

The occurrence of Ethyl 3-methyl-4-oxo-4,5,6,7-tetrahydro-2H-isoindole-1-carboxylate 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.

Ethyl 3-methyl-4-oxo-4,5,6,7-tetrahydro-2H-isoindole-1-carboxylate (CAS 65038-91-7), molecular formula C12H15NO3 and molecular weight 221.25 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C12H15NO3, Ethyl 3-methyl-4-oxo-4,5,6,7-tetrahydro-2H-isoindole-1-carboxylate 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 221.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

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.
