Chemical Structure
Description
CATO manufactures Allyltriphenylphosphonium 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.
Allyltriphenylphosphonium (CAS 15912-76-2), molecular formula C21H20P and molecular weight 303.36 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to organophosphorus functionality, a polycyclic aromatic system, Allyltriphenylphosphonium is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 303.36 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).
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.
