Chemical Structure
Description
CATO supplies Tetramethyl methylenebis(phosphonate) (CAS 16001-93-7), a certified reference material (molecular formula C5H14O6P2, MW 232.11 g/mol) for analytical method development and quality control.
The molecular framework of Tetramethyl methylenebis(phosphonate) (C5H14O6P2) is characterized by a carbohydrate-derived structure, 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.
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), Tetramethyl methylenebis(phosphonate) 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.
