Description
As a certified reference material (CRM), Benzenemethanamine,2-amino-N,N-bis[(2-aminophenyl)methyl]- 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.
Benzenemethanamine,2-amino-N,N-bis[(2-aminophenyl)methyl]- (CAS 222638-73-5), molecular formula C21H24N4 and molecular weight 332.44 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Benzenemethanamine,2-amino-N,N-bis[(2-aminophenyl)methyl]- (C21H24N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 332.44 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
