Chemical Structure
Description
The molecular framework of 2,2'-((2-(Bis(phosphonomethyl)amino)ethyl)azanediyl)diacetic acid (C8H18N2O10P2) is characterized by a carbohydrate-derived structure, an amide group, a phosphate ester group. 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.
2,2'-((2-(Bis(phosphonomethyl)amino)ethyl)azanediyl)diacetic acid (CAS 57991-20-5), molecular formula C8H18N2O10P2 and molecular weight 364.18 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
