Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
[4-(Decanoylamino)benzyl]phosphonic acid (GWJ-23 (CAS 1351930-95-4), molecular formula C17H26NO4PNa and molecular weight 362.36 g/mol, is a CATO reference standard with documented purity and traceability.
[4-(Decanoylamino)benzyl]phosphonic acid (GWJ-23 (C17H26NO4PNa) contains a steroid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. 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).
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.
