Solvent. Softener. Organic synthesis. Chromatographic analysis reagents. In agricultural analysis, it is used as a developing agent for paper chromatography for the analysis of amino acid contents in rice. Amides have active reactivity and special solubility capabilities, and can be used as organic synthesis raw materials, paper treatment agents, softeners in the fiber industry, softeners for animal glue, and also as analytical reagents for determining amino acid contents in rice. In organic synthesis, its applications in the pharmaceutical field are predominant, and it also has many uses in pesticides, dyes, pigments, fragrances, and additives. It is also an excellent organic solvent, mainly used in the spinning of acrylonitrile copolymers and ion exchange resins, as well as anti-static coating or conductive coating for plastic products, etc. In addition, it is used for separating chlorosilanes and purifying oils and fats. Formamide can undergo various reactions, in addition to reacting with three hydrogens, it can also undergo dehydration, CO removal, amino introduction, acyl group introduction, and cyclization reactions. For example, cyclization. Diethyl malonate reacts with formamide to obtain the intermediate 4,6-dihydroxy pyrimidine of vitamin B4. p-Aminobenzoic acid reacts with amide to obtain the intermediate quinazolone-4 of anti-arrhythmic quinoline.
