The molecular framework of PHO21X9SHC 34690-00-1 P,P',P'',P'''-(((Phosphonomethyl)imino)bis(6,1-hexanediylnitrilobis(methylene)))tetrakisphosphonic acid (((Phosphonomethyl)imino)bis(hexamethylenenitrilobis(methylene)))tetrakisphosphonic acid Phosphonic acid, P,P',P'',P'''-(((phosphonomethyl)imino)bis(6,1-hexanediylnitrilobis(methylene)))tetrakis- Phosphonic acid, (((phosphonomethyl)imino)bis(6,1-hexanediylnitrilobis(methylene)))tetrakis- Bishexamethylenetriamine, pentamethylenepentaphosphonic acid EINECS 252-156-6 (((Phosphonomethyl)imino)bis(6,1-hexanediylnitrilobis(methylene)))tetrakisphosphonic acid UNII-PHO21X9SHC EC 252-156-6 (C17H44N3O15P5) is characterized by an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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. 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.
