Chemical Structure
Description
4-Hydrazinyl-5,6-dimethylpyrimidine (CAS 69142-11-6), molecular formula C6H10N4 and molecular weight 138.17 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, an aromatic ring system, 4-Hydrazinyl-5,6-dimethylpyrimidine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 138.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 4-Hydrazinyl-5,6-dimethylpyrimidine 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.
