Chemical Structure
Description
CATO supplies Methyl-d3-triphenylphosphonium Iodide (CAS 1560-56-1), a certified reference material (molecular formula C19H15D3PI, MW 407.25 g/mol) for analytical method development and quality control.
Structurally, Methyl-d3-triphenylphosphonium Iodide (C19H15D3PI) contains deuterium isotope labeling, organophosphorus functionality, iodine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 407.25 g/mol, it falls into the moderately-high-molecular-weight range. 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.
