{[4-(difluoromethoxy)-3-methoxybenzoyl]amino}acetic acid CAS 851288-85-2

Description

As a certified reference material (CRM), {[4-(difluoromethoxy)-3-methoxybenzoyl]amino}acetic acid 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.

{[4-(difluoromethoxy)-3-methoxybenzoyl]amino}acetic acid (CAS 851288-85-2), molecular formula C11H11F2NO5 and molecular weight 275.21 g/mol, is a CATO reference standard with documented purity and traceability.

{[4-(difluoromethoxy)-3-methoxybenzoyl]amino}acetic acid (C11H11F2NO5) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine 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.
