Description
As a certified reference material (CRM), Potassium tetrakis(4-tert-butylphenyl)borate 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.
Potassium tetrakis(4-tert-butylphenyl)borate (CAS 401818-78-8), molecular formula C40H52BK and molecular weight 582.76 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Potassium tetrakis(4-tert-butylphenyl)borate (C40H52BK) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 582.76 g/mol, it falls into the moderately-high-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.
