Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Propane-1,3-diylbis((3-methylbut-2-en-1-yl)diphenylphosphonium) chloride.
Propane-1,3-diylbis((3-methylbut-2-en-1-yl)diphenylphosphonium) chloride (CAS 81194-91-4), molecular formula C37H44P2 and molecular weight 550.69 g/mol, is a CATO reference standard with documented purity and traceability.
Propane-1,3-diylbis((3-methylbut-2-en-1-yl)diphenylphosphonium) chloride (C37H44P2) contains organophosphorus functionality, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures Propane-1,3-diylbis((3-methylbut-2-en-1-yl)diphenylphosphonium) chloride 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.
