Chemical Structure

2-(3,5-dioxo-1,2,4-triazolidin-4-yl)acetic acid CAS 78409-55-9 chemical structure

Description

CATO supplies 2-(3,5-dioxo-1,2,4-triazolidin-4-yl)acetic acid (CAS 78409-55-9), a certified reference material (molecular formula C4H5N3O4, MW 159.10 g/mol) for analytical method development and quality control.

2-(3,5-dioxo-1,2,4-triazolidin-4-yl)acetic acid (C4H5N3O4) contains a carbohydrate-derived structure, an amide group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
