P-Aminobenzoic Acid is one of the most important aromatic amino acids, is an important part of the body's cell growth and division of the substances necessary for the growth of an irreplaceable role in the metabolism of life, in yeast, liver, bran, malt content is very high.4-aminobenzoic acid can alleviate the lack of red blood cells and lead to anemia, viral anemia, stomatitis diarrhea, and anemia in pregnancy, etc..4-aminobenzoic acid As the main ingredient of the highly effective nutrient - Vitamin B-100 Complex, it can effectively improve the body's three major metabolism, and comprehensively fight fatigue and relieve stress.4-Aminobenzoic AcidChemicalbookcarboxylic Acid and Penicillin or Streptomycin are paired together, which can effectively improve the bacteriostatic effect. ApplicationP-aminobenzoic acid is also an important fine chemical raw material, in medicine, is the synthesis of blood tonic - folic acid, procoagulant - p-carboxybenzylamine key Intermediates, but also used in the manufacture of drugs for the treatment of rickets, rheumatism, arthritis, tuberculosis. In the cosmetic industry, it is an important sunscreen agent, hair growth agent intermediate; in the organic chemical industry, it is used to prepare a variety of ester products, can be used as a resin modifier, and can also be used for the synthesis of reactive dyes, azodyes, special intermediates.

Company information

The company's main import and export products include

(1)Intermediates：Intermediates are semi-finished products, which are products in the middle of the production of certain products, for example, to produce a product, which can be produced from intermediates to save costs.Intermediates are available from cyclic compounds such as benzene, naphthalene, anthracene, etc. by sulfonation, alkali fusion, nitration, reduction and other reactions.Our Intermediates products include pharmaceutical intermediates, Pesticide Intermediates and dye intermediates.

(2)Organic Raw Materials：It has a wide range of uses, which can be divided into three aspects: first, it is used as a raw material for the production of polymer chemical products, i.e., monomers for polymerisation reactions; second, it is used as a raw material for other organic chemical industries, including fine chemical products; and third, it is used as a solvent, refrigerant, antifreeze, and gas adsorbent. Basic organic chemical industry is the basis for the development of the production of various organic chemical products, is the main component of the modern industrial structure.
