Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 164.57 g/mol gives 3-Fluoro-6-hydrazinylpyridazine hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Fluoro-6-hydrazinylpyridazine hydrochloride (CAS 2089377-18-2), molecular formula C4H5FN4HCl and molecular weight 164.57 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C4H5FN4HCl, 3-Fluoro-6-hydrazinylpyridazine hydrochloride contains a nitrile group, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 164.57 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-Fluoro-6-hydrazinylpyridazine hydrochloride 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.
