Chemical Structure

5-Hydrazinyl-8-methylpyrido[2,3-d]pyridazine CAS 90223-58-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 175.19 g/mol gives 5-Hydrazinyl-8-methylpyrido[2,3-d]pyridazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Hydrazinyl-8-methylpyrido[2,3-d]pyridazine (CAS 90223-58-8), molecular formula C8H9N5 and molecular weight 175.19 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Hydrazinyl-8-methylpyrido[2,3-d]pyridazine (C8H9N5) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 5-Hydrazinyl-8-methylpyrido[2,3-d]pyridazine 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.
