Some novel 3-halo-6-(4-substituted-phenoxy)pyridazines and 3,6-di-(4- substituted-phenoxy)pyridazines were synthesized from 3,6-dichloropyridazine or 3,6-diiodopyridazine. 3,6-Diiodopyridazine was prepared from 3,6- dichloropyridazine using hydriodic acid/iodine monochloride.

Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. A catalyst does not appear in the overall stoichiometry of the reaction it catalyzes. “Application of 17321-35-6

A novel process is described for preparing substituted pyridazines, where a less substituted pyridazine is reacted with a carboxylic acid in the presence of a silver ion as catalyst, using peroxydisulfate ion. The reaction is run at a temperature from about 40 to 80 C. in an aqueous solvent system and mineral acid. The substituted pyridazines are useful as intermediates to herbicidal and fungicidal compounds.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 22808-29-3 is helpful to your research. Reference of 22808-29-3

Chemistry involves the study of all things chemical – chemical processes, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations. Computed Properties of C7H6Cl2N2O2

Inhibition of spleen tyrosine kinase has attracted much attention as a mechanism for the treatment of cancers and autoimmune diseases such as asthma, rheumatoid arthritis, and systemic lupus erythematous. We report the structure-guided optimization of pyridazine amide spleen tyrosine kinase inhibitors. Early representatives of this scaffold were highly potent and selective but mutagenic in an Ames assay. An approach that led to the successful identification of nonmutagenic examples, as well as further optimization to compounds with reduced cardiovascular liabilities is described. Select pharmacokinetic and in vivo efficacy data are presented.

Healthcare careers for chemists are once again largely based in laboratories, although increasingly there is opportunity to work at the point of care, helping with patient investigation. Reference of 5788-58-9

The present invention describes pyridazinone compounds of formula I which are cyclooxygenase (COX) inhibitors, and in particular, are selective inhibitors of cyclooxygenase-2 (COX-2). COX-2 is the inducible isoform associated with inflammation, as opposed to the constitutive isoform, cyclooxygenase-1 (COX-1) which is an important ?housekeeping? enzyme in many tissues, including the gastrointestinal (GI) tract and the kidneys. The selectivity of these compounds for COX-2 minimizes the unwanted GI and renal side-effects seen with currently marketed non-steroidal anti-inflammatory drugs (NSAIDs).
