Chemical Structure
Description
1,1,2,2-Tetraphenylhydrazine (CAS 632-52-0) is a high-purity analytical reference standard with the molecular formula C24H20N2 and a molecular weight of 336.43 g/mol.
1,1,2,2-Tetraphenylhydrazine (C24H20N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 1,1,2,2-Tetraphenylhydrazine 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.
