Chemical Structure
Description
1,4-Dimethylpyrazole (C5H8N2) contains a nitrile group. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
1,4-Dimethylpyrazole (CAS 1072-68-0), molecular formula C5H8N2 and molecular weight 96.13 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), 1,4-Dimethylpyrazole 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.
