Chemical Structure

3-Amino-5-methyl-5-(2-phenylethyl)imidazolidine-2,4-dione CAS 956437-87-9 chemical structure

Description

The molecular framework of 3-Amino-5-methyl-5-(2-phenylethyl)imidazolidine-2,4-dione (C12H15N3O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies 3-Amino-5-methyl-5-(2-phenylethyl)imidazolidine-2,4-dione (CAS 956437-87-9), a certified reference material (molecular formula C12H15N3O2, MW 233.27 g/mol) for analytical method development and quality control.

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.
