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 (2-Fluoropyridin-3-yl)dimethylphosphine oxide.
CATO supplies (2-Fluoropyridin-3-yl)dimethylphosphine oxide (CAS 2567502-51-4), a certified reference material (molecular formula C7H9FNOP, MW 173.12 g/mol) for analytical method development and quality control.
The molecular framework of (2-Fluoropyridin-3-yl)dimethylphosphine oxide (C7H9FNOP) is characterized by an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
