Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
[(2,5-dichlorophenyl)methyl]triphenylphosphanium chloride (CAS 1485415-16-4) is a high-purity analytical reference standard with the molecular formula C25H20Cl2PCl and a molecular weight of 457.76 g/mol.
Owing to organophosphorus functionality, chlorine substitution, a polycyclic aromatic system, [(2,5-dichlorophenyl)methyl]triphenylphosphanium chloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 457.76 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
