Chemical Structure
Description
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.
(RS)-Ppg 120667-15-4 2-amino-2-(4-phosphonophenyl)acetic acid (CAS 120667-15-4) is a high-purity analytical reference standard with the molecular formula C8H10NO5P and a molecular weight of 231.14 g/mol.
(RS)-Ppg 120667-15-4 2-amino-2-(4-phosphonophenyl)acetic acid (C8H10NO5P) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
