Chemical Structure
Description
The molecular framework of 2-Aminoethyl dihydrogen phosphate calcium salt (2:1) (C2H7NO4PCa) is characterized by an amide group, a phosphate ester group, a carboxylic acid 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.
2-Aminoethyl dihydrogen phosphate calcium salt (2:1) (CAS 18672-70-3) is a high-purity analytical reference standard with the molecular formula C2H7NO4PCa and a molecular weight of 180.13 g/mol.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 2-Aminoethyl dihydrogen phosphate calcium salt (2:1) 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.
