What is 4-Aminobenzoic acid?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is 4-Aminobenzoic acid which has developed particularly rapidly in recent years. Do you know about 4-Aminobenzoic acid ?
- The official answer：4-Aminobenzoic acid, one of the most important aromatic amino acids, is an essential component of substances necessary for cell growth and division in the body and has an irreplaceable role in the metabolism of life. 4-Aminobenzoic acid can relieve anemia caused by red blood cell deficiency, viral anemia, stomatitis diarrhea, and anemia during pregnancy. 4-Aminobenzoic acid Vitamin B-100 complex, a highly effective nutrient as the main ingredient, can effectively improve the body’s three major metabolisms and comprehensively fight fatigue and relieve stress. 4-aminobenzoic acid and penicillin or streptomycin are paired to effectively improve the antibacterial effect.
What’s the application of 4-Aminobenzoic acid?
- Aminobenzoic acid is also an important fine chemical material, in medicine, it is a key intermediate in the synthesis of blood tonic – folic acid, pro-coagulant – p-carboxybenzylamine, and also used in the manufacture of drugs for the treatment of rickets, rheumatism, arthritis, tuberculosis. In the cosmetic industry, it is an important intermediate for human sunscreen and hair growth agents; in the organic chemical industry, it is used to prepare various esters and can be used as a resin modifier, and also used as a special intermediate for the synthesis of reactive dyes and azo dyes. Used as intermediates of medicine, dyestuff intermediates dyestuff, and medicine intermediates. Used in the production of reactive red M-80, M-10B, reactive red-violet X-2R, and other dyestuffs as well as the production of cyanobenzoic acid to produce the drug p-carboxybenzylamine. P-aminobenzoic acid can be used as a sunscreen, its derivatives p-dimethyl carbamic acid octyl ester, is an excellent sunscreen, trade name PadimateO.WidelydistributedinnatureasaBcomplexfactor.Bakeryeastcontains5to6ppm,breweryeastfrom10to100ppm.Occursfreeandinesterform.Used as a reagent for the determination of copper. It is used in the synthesis of esters, folic acid, and azo dyes. Use as an analytical reagent, sunscreen, also used in the pharmaceutical and dye industry
