<p>Pyridine, 3-(1,1-dimethylethyl)- is a ligand that binds to anions. It has been used as a catalyst for the synthesis of vinyl ethers and lactams. Pyridine, 3-(1,1-dimethylethyl)- can be formed from 1-pyridinium ion (from the oxidation of pyridine) and 2-propenal. This reaction is catalyzed by silver ions in the presence of light or heat. Pyridine, 3-(1,1-dimethylethyl)- is also a component of polymer matrices for solar cells.</p>

<p>4,5-Dibromothiophene-2-carbaldehyde is a dehalogenation agent that can be used to convert bromides to thiols. It is a versatile reagent that can be used in Suzuki and coupling reactions with minimal effort. The regioselective use of this reagent has been shown using the coupling of 2,6-dibromo-4-methylthiophene and benzaldehyde.</p>

<p>N-Desmethyl azatadine is a piperidinecarboxylic acid, which is an active metabolite of the antihistamine loratadine and the decongestant azatadine. It is used in the treatment of chronic cough associated with reflux. N-Desmethyl azatadine has been shown to be effective in reducing symptoms of chronic cough in patients with gastroesophageal reflux disease (GERD) or symptomatic GERD. This drug binds to histamine H1 receptors, inhibiting histamine binding and blocking its effects on the body. N-Desmethyl azatadine also inhibits the production of acid by bacteria in the stomach, decreasing acidity and improving symptoms of GERD.</p>
