Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including ((3,4-dimethoxypyridin-2-yl)methyl)triphenylphosphonium chloride.
((3,4-dimethoxypyridin-2-yl)methyl)triphenylphosphonium chloride (CAS 2509218-03-3) is a high-purity analytical reference standard with the molecular formula C26H25NO2PCl and a molecular weight of 449.92 g/mol.
Owing to a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution, ((3,4-dimethoxypyridin-2-yl)methyl)triphenylphosphonium chloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 449.92 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
