Chemical Structure
Description
CATO supplies Methylenediphosphonic Acid (CAS 1984-15-2), a certified reference material (molecular formula CH6O6P2, MW 176.00 g/mol) for analytical method development and quality control.
The molecular framework of Methylenediphosphonic Acid (CH6O6P2) is characterized by a phosphate ester group. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
