4-Dimethylaminopyridine

Product name: 4-Dimethylaminopyridine CAS RN: 1122-58-3 EINECS Number: 219-282-3 Molecular formula: C7H10N2 Molecular weight: 122.168 Physical and chemical properties: White crystalline powder. It is light yellow flaky crystal precipitated from ether. It is insoluble in water (7.6), hexane, cyclohexane, soluble in ethanol, benzene, chloroform, methanol, ethyl acetate, acetone, acetic acid and dichloroethane. Quality index: Purity: ≥99% (HPLC) Loss on drying: ≤0.5% Packaging: 25KG/barrel Uses: As a new type of high-efficiency catalyst, it can significantly catalyze the acylation (phosphorylation, sulfonylation, carbonylation) reactions of alcohols and amines with high steric hindrance and low reactivity. It has high catalytic performance in many types of reactions such as acylation, alkylation, etherification, esterification and transesterification in organic synthesis, drug synthesis, pesticides, medicines, dyes, fragrances, polymer chemistry, and analytical chemistry. ability, which has a very obvious effect on improving the yield. Storage: in a cool dry place.
