Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Naphthalen-2-yltriphenylsilane (CAS 18768-93-9), a certified reference material (molecular formula C28H22Si, MW 386.56 g/mol) for analytical method development and quality control.
Owing to a polycyclic aromatic system, Naphthalen-2-yltriphenylsilane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 386.56 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.
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.
