Chemical Structure

2,5-Diamino-1-methyl-1H-imidazol-4(5H)-one CAS 920763-94-6 chemical structure

Description

The molecular framework of 2,5-Diamino-1-methyl-1H-imidazol-4(5H)-one (C4H8N4O) is characterized by 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

2,5-Diamino-1-methyl-1H-imidazol-4(5H)-one (CAS 920763-94-6), molecular formula C4H8N4O and molecular weight 128.13 g/mol, is a CATO reference standard with documented purity and traceability.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 2,5-Diamino-1-methyl-1H-imidazol-4(5H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
