Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Bis[2-(perfluorooctyl)ethyl] phosphate.
CATO supplies Bis[2-(perfluorooctyl)ethyl] phosphate (CAS 678-41-1), a certified reference material (molecular formula C20H9F34O4P, MW 990.20 g/mol) for analytical method development and quality control.
Structurally, Bis[2-(perfluorooctyl)ethyl] phosphate (C20H9F34O4P) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of -0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 990.20 g/mol, it falls into the high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
