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.
CATO supplies ((3-Methylnaphthalen-1-yl)methyl)triphenylphosphonium bromide (CAS 77028-94-5), a certified reference material (molecular formula C30H26PBr, MW 497.42 g/mol) for analytical method development and quality control.
Owing to organophosphorus functionality, bromine substitution, a polycyclic aromatic system, ((3-Methylnaphthalen-1-yl)methyl)triphenylphosphonium bromide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 497.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
