Chemical Structure
Description
The occurrence of Ethyl 4-fluoro-2-methyl-3-oxobutanoate is closely related to an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 4-fluoro-2-methyl-3-oxobutanoate (CAS 685-84-7) is a high-purity analytical reference standard with the molecular formula C8H20NO6P2Na and a molecular weight of 311.19 g/mol.
Ethyl 4-fluoro-2-methyl-3-oxobutanoate (C8H20NO6P2Na) contains an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 4-fluoro-2-methyl-3-oxobutanoate 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.
