6-(Bis(phosphonomethyl)amino)hexanoic acid CAS 55628-97-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-(Bis(phosphonomethyl)amino)hexanoic acid.

6-(Bis(phosphonomethyl)amino)hexanoic acid (CAS 55628-97-2), molecular formula C8H19NO8P2 and molecular weight 319.19 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 6-(Bis(phosphonomethyl)amino)hexanoic acid (C8H19NO8P2) contains a carbohydrate-derived structure, an amide group, a phosphate ester group. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 319.19 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

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.
