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 (4-Fluorophenyl)dimethylphosphine oxide.
CATO supplies (4-Fluorophenyl)dimethylphosphine oxide (CAS 18437-74-6), a certified reference material (molecular formula C8H10FOP, MW 172.14 g/mol) for analytical method development and quality control.
Owing to organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine substitution, (4-Fluorophenyl)dimethylphosphine oxide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 172.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
