Products Description of 4-Dimethylaminopyridine CAS#1122-58-34-dimethylaminopyridine, commonly referred to as DMAP, is a strong nucleophilic acylation catalyst. The resonance of the electron-donating dimethylamino group with the parent ring (pyridine ring) can strongly activate the nitrogen atoms on the ring for nucleophilic substitution, and significantly catalyze the acylation/esterification of alcohols and amines/acids with high resistance and low reactivity, with the activity of about 104~106 times that of pyridine.

Products Description of 4-Bromopyridine hydrochlorideCAS#19524-06-24-Bromopyridine hydrochloride is a white crystalline solid at room temperature and pressure. It has a certain degree of hygroscopicity and is easily deliquescent in water. It is often used as a coupling reagent and a precursor molecule of pyridine derivatives in organic synthetic chemistry. When used, it is often pre-treated with alkali to release 4-bromopyridine.

Products Description of Tetrahydro-4-pyranol CAS#2081-44-9Tetrahydropyran-4-ol is a colorless transparent liquid at room temperature and pressure. It has good polarity and hydrophilicity and can be used as a solvent in organic synthesis. The structure of tetrahydropyran-4-ol contains a tetrahydropyran unit and an active hydroxyl structure, and has high chemical reactivity and diverse chemical conversion properties. The tetrahydropyran-4-ol molecule contains a hydroxyl structure, so it has a certain polarity.

Products Description of 4-AminophenolCAS#123-30-8Aminophenol is also known as hydroxyaniline and aminohydroxybenzene. There are three isomers, namely o-aminophenol, m-aminophenol and p-aminophenol (4-aminophenol). In 1874, Baeyer et al. first prepared p-aminophenol. Due to the different relative positions of the hydroxyl group and the amino group, the three are also different in terms of physical and chemical properties. This product is weakly alkaline, weakly acidic and strongly reducing. Because it has both amino and phenol groups, it has the common properties of both.

Products Description of Imidazole CAS#288-32-4 Imidazole, with the molecular formula C3H4N2, is an organic compound, a type of diazole, and a five-membered aromatic heterocyclic compound containing two meta-nitrogen atoms in the molecular structure. The unshared electron pair of the 1-nitrogen atom in the imidazole ring participates in the cyclic conjugation, and the electron density of the nitrogen atom is reduced, making it easy for the hydrogen on this nitrogen atom to leave in the form of hydrogen ions.Imidazole is acidic and alkaline, and can form salts with strong bases.
