Chemical Structure
Description
Ethyl 2-bromo-5-fluorobenzimidate (CAS 1260849-11-3), molecular formula C9H9BrFNO and molecular weight 246.08 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Ethyl 2-bromo-5-fluorobenzimidate (C9H9BrFNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 246.08 g/mol, it falls into the medium-molecular-weight range. 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-5-fluorobenzimidate 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.
