Chemical Structure
Description
5-Amino-4H-1,2,4-triazole-3-carbonitrile (CAS 1016798-54-1), molecular formula C3H3N5 and molecular weight 109.09 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5-Amino-4H-1,2,4-triazole-3-carbonitrile (C3H3N5) contains a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 109.09 g/mol, it falls into the low-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.
As a certified reference material (CRM), 5-Amino-4H-1,2,4-triazole-3-carbonitrile 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.
