4-Pyridazinecarboxylic acid Chemical Properties,Usage,Production

Chemical Properties

Off-white to brown powder

Uses

4-Pyridazinecarboxylic Acid is the pyridazine analog of Nicotinic Acid (N429250). 4-Pyridazinecarboxylic Acid is a glutamate racemase inhibitor. It is also used in characterization study of nicotinic acid receptors in mouse macrophages

Definition

4-Pyridazinecarboxylic acid is a derivative of Pyridazine which has highly π-deficient aromatic character can be used as electron-withdrawing part into push-pull structures favoring the intramolecular charge transfer (ICT)[2].

General Description

Surface electrochemical studies of 4-pyridazinecarboxylic acid adsorbed at Pt(111) surfaces by electron energy-loss and Auger spectroscopy has been reported.

Structure and conformation

Pnma(no. 62), a= 11.165(2) Å, b= 6.215(1) Å, c= 7.413(2)Å, V= 514.4 Å3, Z=4, Rgt(F)= 0.0567, wRref(F2)= 0.1515, T= 153K[1].
