Chemical Structure
Description
As a certified reference material (CRM), Diethyl Butylphosphonate 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.
Diethyl Butylphosphonate (CAS 2404-75-3), molecular formula C8H19O3P and molecular weight 194.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Diethyl Butylphosphonate (C8H19O3P) is characterized by a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
