Chemical Structure
Description
As a certified reference material (CRM), 2-Amino-5-phenylimidazole 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.
2-Amino-5-phenylimidazole (CAS 6775-40-2), molecular formula C9H9N3 and molecular weight 159.19 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 2-Amino-5-phenylimidazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 159.19 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
