1. Salicylic acid namely ortho hydroxy benzoic acid (o-hydroxybenzoic acid) is a kind of important organic synthetic raw material. In pesticide production, it is used for synthetic organic phosphorus pesticide Isocarbophos, isofenphos methyl intermediates isopropyl salicylate and Rodenticide warfarin, kill rats ether intermediate 4-hydroxy coumarin; in the pharmaceutical industry, salicylic acid was used as antiseptics, also as intermediates of acetylsalicylic acid (aspirin) and other drugs; it is also an important raw material of dye, spices, such as rubber industry .
2.It is mainly used as raw materials of aspirin feedstock and pesticide aqueous amine and phosphorus products, can also be used in dye industry, refining and chemical reagent, etc.
3.Used in the pharmaceutical industry for the antipyretic, analgesic, anti-inflammatory, diuretic drugs, industrial dye used for direct of azo dyes and acid mordant dyes, but also for spices, etc.
4.Used as complexing indicator and preservative.
5.Verification for aluminum, boron, cerium, copper, iron, lead, manganese, mercury, nickel, silver, titanium, tungsten, vanadium, sulfite, nitrate and nitrite. Determination of aluminum, copper, iron, thorium, titanium and uranium. Alkali method and iodometry titration standard. The fluorescent indicator. Complexometric indicator.
