Chemical Structure
Description
Owing to a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, Dibut-1-yl Methylphosphonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 208.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
Dibut-1-yl Methylphosphonate (CAS 2404-73-1), molecular formula C9H21O3P and molecular weight 208.24 g/mol, is a CATO reference standard with documented purity and traceability.
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), Dibut-1-yl Methylphosphonate 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.
