Chemical Structure
Description
The occurrence of 4-pyridylhydrazine;dihydrochloride is closely related to a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-pyridylhydrazine;dihydrochloride (CAS 106898-34-4), molecular formula C5H7N3HCl and molecular weight 145.59 g/mol, is a CATO reference standard with documented purity and traceability.
4-pyridylhydrazine;dihydrochloride (C5H7N3HCl) contains a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; 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.
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), 4-pyridylhydrazine;dihydrochloride 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.
