Compared with other compounds in its class, the molecular weight of 429.89 g/mol gives [(1H-Benzotriazol-1-yl)methyl]triphenylphosphonium Chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies [(1H-Benzotriazol-1-yl)methyl]triphenylphosphonium Chloride (CAS 111198-09-5), a certified reference material (molecular formula C25H21N3PCl, MW 429.89 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality, chlorine substitution, [(1H-Benzotriazol-1-yl)methyl]triphenylphosphonium Chloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 429.89 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
