Applications

1. Pharmaceutical Field: It has antioxidant, anti-inflammatory, antibacterial and other biological activities, and is used as a raw material for the synthesis of anti-inflammatory, anti-tumor and neuroprotective drugs; it can also be used as an intermediate for pharmaceutical synthesis to optimize the efficacy and bioavailability of drugs.
2. Cosmetics Field: As a natural antioxidant, it can inhibit the oxidation of skin cells, delay skin aging, and is widely added to skin care products such as lotions, creams and serums to improve skin texture and enhance skin resistance.
3. Food Additive Field: It can be used as a food antioxidant and preservative to extend the shelf life of food; it can also be used as a food flavoring agent to increase the unique flavor of food.
4. Organic Synthesis Field: It can undergo addition, substitution, condensation and other reactions, and is used as a building block for the synthesis of various fine chemicals; it can also be used as a standard substance and reagent in analytical chemistry experiments.
5. Other Fields: It is used in the preparation of photosensitive materials, coatings and other products, and can also be used as a plant growth regulator to promote plant growth.

Safety Information

• Hazard Category: Irritant (GHS hazard symbol: GHS07; hazard code: R36/37/38)
• Hazards: It is irritating to the skin, eyes and respiratory tract. Direct contact may cause skin redness, itching, dryness and other discomfort; eye contact may lead to conjunctival hyperemia, burning and other symptoms; inhalation of dust may cause respiratory tract irritation, cough, chest tightness and other discomfort.
• Operation Precautions: All operations shall be carried out in a well-ventilated fume hood; wear nitrile gloves, acid and alkali resistant protective clothing, safety goggles and dust mask to avoid direct contact and inhalation of dust.
• Storage Requirements: Seal tightly and store in a cool, dry, dark and well-ventilated place; avoid moisture, light and high temperature; separate from strong oxidants and strong acids to prevent chemical reactions; do not mix storage and transportation.
• Waste Disposal: Waste residues and contaminated packaging shall be disposed of in strict accordance with the management regulations of hazardous chemicals, and shall not be directly discharged into water bodies, soil or sewers to avoid environmental pollution.
• First Aid Measures: In case of skin contact, rinse immediately with plenty of clean water for at least 15 minutes; in case of eye contact, rinse with plenty of water for 15 minutes and seek medical advice in time; in case of accidental ingestion, do not induce vomiting and seek medical treatment immediately with the product label.
