Description
As a certified reference material (CRM), butyl 2-cyano-3-(dibutoxyphosphoryl)propanoate 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.
butyl 2-cyano-3-(dibutoxyphosphoryl)propanoate (CAS 22730-56-9), molecular formula C8H9BO3 and molecular weight 163.97 g/mol, is a CATO reference standard with documented purity and traceability.
butyl 2-cyano-3-(dibutoxyphosphoryl)propanoate (C8H9BO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
