Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 2-bromo-2-(diethoxyphosphoryl)acetate.
CATO supplies Ethyl 2-bromo-2-(diethoxyphosphoryl)acetate (CAS 23755-73-9), a certified reference material (molecular formula C8H16BrO5P, MW 303.09 g/mol) for analytical method development and quality control.
Ethyl 2-bromo-2-(diethoxyphosphoryl)acetate (C8H16BrO5P) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), Ethyl 2-bromo-2-(diethoxyphosphoryl)acetate 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.
