Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-{6-[(2,4-dichlorophenyl)methyl]pyridazin-3-yl}-4-(4-fluorophenyl)-1H-pyrazol-5-amine.
CATO supplies 1-{6-[(2,4-dichlorophenyl)methyl]pyridazin-3-yl}-4-(4-fluorophenyl)-1H-pyrazol-5-amine (CAS 321385-80-2), a certified reference material (molecular formula C20H14Cl2FN5, MW 414.26 g/mol) for analytical method development and quality control.
Structurally, 1-{6-[(2,4-dichlorophenyl)methyl]pyridazin-3-yl}-4-(4-fluorophenyl)-1H-pyrazol-5-amine (C20H14Cl2FN5) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 414.26 g/mol, it falls into the moderately-high-molecular-weight range. 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).
