2-((5-Amino-1H-1,2,4-triazol-3-yl)methyl)isoindoline-1,3-dione CAS 21733-07-3

Description

The occurrence of 2-((5-Amino-1H-1,2,4-triazol-3-yl)methyl)isoindoline-1,3-dione 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.

CATO supplies 2-((5-Amino-1H-1,2,4-triazol-3-yl)methyl)isoindoline-1,3-dione (CAS 21733-07-3), a certified reference material (molecular formula C11H9N5O2, MW 243.22 g/mol) for analytical method development and quality control.

Based on its molecular formula C11H9N5O2, 2-((5-Amino-1H-1,2,4-triazol-3-yl)methyl)isoindoline-1,3-dione 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 243.22 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.
