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.
CATO supplies Geranylgeranyltriphenylphosphonium Bromide (CAS 57784-37-9), a certified reference material (molecular formula C38H48PBr, MW 615.68 g/mol) for analytical method development and quality control.
Owing to organophosphorus functionality, bromine substitution, a polycyclic aromatic system, Geranylgeranyltriphenylphosphonium Bromide is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 615.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), Geranylgeranyltriphenylphosphonium Bromide 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.
