Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1820748-59-1 Ethyl (2Z)-2-(3-bromo-2-fluorophenyl)-2-hydrazinylideneacetate.
1820748-59-1 Ethyl (2Z)-2-(3-bromo-2-fluorophenyl)-2-hydrazinylideneacetate (CAS 1820748-59-1), molecular formula C10H10BrFN2O2 and molecular weight 289.10 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1820748-59-1 Ethyl (2Z)-2-(3-bromo-2-fluorophenyl)-2-hydrazinylideneacetate (C10H10BrFN2O2) 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 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 289.10 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 1820748-59-1 Ethyl (2Z)-2-(3-bromo-2-fluorophenyl)-2-hydrazinylideneacetate 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.
