Overview of hazards

Physical and chemical hazards: colorless crystals. Miscible with water, alcohol, ether, chloroform, benzene, ethyl acetate and carbon disulfide, and poorly soluble in petroleum ether. It is a colorless polar solvent with a high boiling point and is also an intermediate in organic synthesis. It can form metal salts with alkali metals, metal oxides or alkaline hydroxides. Health hazards: It has a mild irritating effect on the skin, but no absorption effect is observed. Due to the low vapor pressure, the risk of inhalation is very small. However, chronic effects can cause dysfunction of the central nervous system and cause lesions in the respiratory organs, kidneys, and vascular systems.

Environmental hazards: This substance is harmful to the environment, and special attention should be paid to water bodies and the atmosphere. GHS hazard category: According to the "General Rules for Classification and Hazard Communication of Chemicals" (GB13690-2009) and the series of standards for chemical classification, warning labels and warning instructions, this product belongs to severe eye damage/eye irritation-2

Recommended uses of the product: used as solvent and organic synthesis intermediate. Used to make nylon-4 and vinyl pyrrolidone, etc. Mainly used as a solvent for synthetic resins, pesticides, polyols, inks, iodine, etc. It can also be used as a plasticizer for acrylic and acrylic styrene resins, an extractant for aromatic compounds, a decolorizer for kerosene, rosin, fatty acids, and a raw material for the preparation of nylon-4, polyvinyl pyrrolidone, 4-aminobutyric acid and its derivatives, etc.
