Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2-Aminoethyl)triphenylphosphonium bromide hydrobromide.
CATO supplies (2-Aminoethyl)triphenylphosphonium bromide hydrobromide (CAS 73648-13-2), a certified reference material (molecular formula C20H21NPHBrBr, MW 467.18 g/mol) for analytical method development and quality control.
Structurally, (2-Aminoethyl)triphenylphosphonium bromide hydrobromide (C20H21NPHBrBr) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.5, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 467.18 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
