Chemical Structure

5-Methoxy-7-methylpyrido[2,3-d]pyridazin-8(7H)-one CAS 5144-72-9 chemical structure

Description

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.

5-Methoxy-7-methylpyrido[2,3-d]pyridazin-8(7H)-one (CAS 5144-72-9) is a high-purity analytical reference standard with the molecular formula C14H5F25O and a molecular weight of 664.15 g/mol.

The molecular framework of 5-Methoxy-7-methylpyrido[2,3-d]pyridazin-8(7H)-one (C14H5F25O) is characterized by a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), 5-Methoxy-7-methylpyrido[2,3-d]pyridazin-8(7H)-one 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.
