2,4-dimethyl-5-phenylimidazo[1,5-b]pyridazine-7-thiol CAS 54221-54-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,4-dimethyl-5-phenylimidazo[1,5-b]pyridazine-7-thiol.

2,4-dimethyl-5-phenylimidazo[1,5-b]pyridazine-7-thiol (CAS 54221-54-4), molecular formula C14H27N3S and molecular weight 269.45 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C14H27N3S, 2,4-dimethyl-5-phenylimidazo[1,5-b]pyridazine-7-thiol contains a nitrile group, sulfur-containing functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 269.45 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

As a certified reference material (CRM), 2,4-dimethyl-5-phenylimidazo[1,5-b]pyridazine-7-thiol 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.
