4-Amino-5-hydroxy-5-methyl-2-oxo-2,5-dihydro-1H-imidazole-1-carbaldehyde CAS 134419-40-2

Description

The occurrence of 4-Amino-5-hydroxy-5-methyl-2-oxo-2,5-dihydro-1H-imidazole-1-carbaldehyde 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.

4-Amino-5-hydroxy-5-methyl-2-oxo-2,5-dihydro-1H-imidazole-1-carbaldehyde (CAS 134419-40-2) is a high-purity analytical reference standard with the molecular formula C5H7N3O3 and a molecular weight of 157.13 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 4-Amino-5-hydroxy-5-methyl-2-oxo-2,5-dihydro-1H-imidazole-1-carbaldehyde is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 157.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
