Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(1,2,4-Triazol-1-yl)acetonitrile.
CATO supplies 2-(1,2,4-Triazol-1-yl)acetonitrile (CAS 81606-79-3), a certified reference material (molecular formula C4H4N4, MW 108.10 g/mol) for analytical method development and quality control.
Structurally, 2-(1,2,4-Triazol-1-yl)acetonitrile (C4H4N4) 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 108.10 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), 2-(1,2,4-Triazol-1-yl)acetonitrile 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.
