(4-Amino-2-fluoro-5-methoxyphenyl)dimethylphosphine oxide CAS 2883046-99-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 217.18 g/mol gives (4-Amino-2-fluoro-5-methoxyphenyl)dimethylphosphine oxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(4-Amino-2-fluoro-5-methoxyphenyl)dimethylphosphine oxide (CAS 2883046-99-7), molecular formula C9H13FNO2P and molecular weight 217.18 g/mol, is a CATO reference standard with documented purity and traceability.

(4-Amino-2-fluoro-5-methoxyphenyl)dimethylphosphine oxide (C9H13FNO2P) contains an amide group, organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
