Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 172.13 g/mol gives 3,4-Difluorobenzohydrazide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3,4-Difluorobenzohydrazide (CAS 229957-07-7), molecular formula C7H6F2N2O and molecular weight 172.13 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3,4-Difluorobenzohydrazide (C7H6F2N2O) contains an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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 172.13 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
CATO manufactures 3,4-Difluorobenzohydrazide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
