Chemical Structure

4,4-Diphosphonobutanoic acid CAS 64488-79-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,4-Diphosphonobutanoic acid.

4,4-Diphosphonobutanoic acid (CAS 64488-79-5), molecular formula C4H10O8P2 and molecular weight 248.06 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carbohydrate-derived structure, a phosphate ester group, 4,4-Diphosphonobutanoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 248.06 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
