Chemical Structure

(R)-(1-aminoethyl)phosphonic acid CAS 60687-36-7 chemical structure

Description

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.

(R)-(1-aminoethyl)phosphonic acid (CAS 60687-36-7), molecular formula C2H8NO3P and molecular weight 125.06 g/mol, is a CATO reference standard with documented purity and traceability.

(R)-(1-aminoethyl)phosphonic acid (C2H8NO3P) contains an amide group, a phosphonate group, a carboxylic acid 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.

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.
