Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
1-[2-(Di-tert-butylphosphino)phenyl]-3,5-diphenyl-1H-pyrazole (CAS 628333-86-8), molecular formula C29H33N2P and molecular weight 440.56 g/mol, is a CATO reference standard with documented purity and traceability.
1-[2-(Di-tert-butylphosphino)phenyl]-3,5-diphenyl-1H-pyrazole (C29H33N2P) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality. 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.
CATO manufactures 1-[2-(Di-tert-butylphosphino)phenyl]-3,5-diphenyl-1H-pyrazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
