Chemical Structure
Description
(6-Amino-3-fluoro-2-methoxyphenyl)dimethylphosphine oxide (CAS 2750028-91-0), molecular formula C9H13FNO2P and molecular weight 217.18 g/mol, is a CATO reference standard with documented purity and traceability.
(6-Amino-3-fluoro-2-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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (6-Amino-3-fluoro-2-methoxyphenyl)dimethylphosphine oxide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
