Product Description



(1) For pesticides: It can be used to synthesize plant growth regulators such as 5-nitroguaiacol sodium.
(2) For pharmaceuticals: It is used to synthesize various anti-inflammatory and antibacterial drugs, such as guaiacol sulfate potassium (calcium), ibuprofen guaiacol ester, and guaiacol glycerol ether.
(4) For the flavor industry: It can be used directly as a flavor material and also used to manufacture vanillin and artificial musk.
(5) In cosmetics industry, it is used as an antioxidant. It is a phenolic antioxidant with strong antioxidant activity. However, the general addition amount should not be too large, and usually needs to be used in combination with synergists, metal ion chelating agents, etc.
(6) In chemical production, it is also used as other organic synthetic intermediates, as well as a plasticizer, printing oil as an antioxidant, analysis reagent, etc.
