Chemical Properties
1. Acidity: It is a weak organic acid, with a pKa value of 5.91, and its aqueous solution is weakly acidic; it can react with strong bases to form corresponding salts, and the reaction is mild without obvious exothermic phenomenon.
2. Stability: Stable under normal temperature and dry conditions; stable to acids and alkalis, not easy to decompose under general acid-base conditions; unstable when exposed to strong light for a long time, and may undergo slight decomposition. It is not easy to be oxidized by common oxidants, and has good chemical stability.
3. Reactivity: It can undergo cyclization, substitution and other reactions, and is an important intermediate in organic synthesis; it does not react with common organic solvents and inorganic salts, and has good compatibility.
4. Incompatibility: Incompatible with strong oxidizing agents; avoid mixed storage to prevent chemical reactions; it is stable when mixed with common pesticides and chemical reagents.
Usage
1. Agricultural field: It is a broad-spectrum systemic fungicide and soil disinfectant, with low toxicity and environmental friendliness. It is mainly used to control soil-borne diseases caused by Fusarium, Pythium, Rhizoctonia and other pathogenic fungi, such as rice seedling blight, beet root rot, tomato stem rot, etc. It also has the function of plant growth regulation, which can promote plant growth and improve crop yield and quality.
2. Pharmaceutical field: Used as an intermediate in the synthesis of pharmaceutical compounds, and also used in the research and development of antibacterial and antiviral drugs; it can be used as an auxiliary reagent in pharmaceutical analysis and detection.
3. Industrial field: Used as an intermediate in the synthesis of organic compounds, and also used in the production of fine chemicals, dyes and other products; it can be used as a solvent auxiliary in industrial production due to its good solubility.
4. Research field: Widely used in agricultural and chemical research, such as the research on the mechanism of fungicidal action, the development of new fungicides, and the research on organic synthesis reactions; for professional research, industrial and agricultural use only.
Storage
Store in a sealed container, keep away from light, heat and moisture; store in a cool, dry and well-ventilated warehouse, the recommended storage temperature is 2-8°C, and refrigerated storage is preferred to maintain stability. It should be stored separately from oxidants and other incompatible substances, and should not be mixed for storage; avoid long-term exposure to strong light to prevent discoloration and decomposition. The storage period can reach 2 years under proper storage conditions.
Safety Overview
Hazard Category: Irritant (Xi); Low toxicity; Causes mild skin irritation (H315), mild eye irritation (H319); Light sensitive. It is for professional agricultural, manufacturing, research laboratories and industrial/commercial use only; when used as an agricultural fungicide, it must comply with relevant national agricultural chemical standards.
Safety Precautions
1. Personal Protection: Wear protective gloves, safety goggles and dust mask when handling; avoid direct contact with skin, eyes and respiratory tract; ensure adequate ventilation in the operation area to avoid inhalation of powder.
2. Emergency Handling: If contact with skin, rinse thoroughly with plenty of flowing water for 5-10 minutes; if contact with eyes, rinse cautiously with water for several minutes (remove contact lenses if present) and continue rinsing, seek medical advice if discomfort occurs; if inhaled, move to fresh air immediately; if swallowed, call a poison center or doctor if feeling unwell.
3. Fire & Spill: Non-flammable; use dry powder, foam, carbon dioxide or water spray to put out fire in case of fire; if spilled, isolate the contaminated area, wear protective equipment, collect the spilled crystals or powder with dry and clean tools, put it into a sealed container for proper disposal, and avoid entering drains or water courses.
4. Disposal: Dispose of waste and packaging in accordance with local environmental and agricultural regulations; do not discard at will; if it is used as an agricultural fungicide, the waste shall be disposed of in accordance with agricultural chemical waste disposal regulations to avoid environmental pollution.
