n-Butylamine

　　Main Uses

　　Agricultural Field:

　　As a fungicide and preservative: sec-Butylamine is a highly efficient preservative for fruits and vegetables, capable of inhibiting the growth of molds (such as Penicillium and green mold) and extending the storage period (e.g., used for the preservation of citrus, apples, pears, etc.). Its principle is to inhibit the metabolic enzyme activity of microbial cells, thereby preventing fungal reproduction.

　　Pesticide intermediate: Used in the synthesis of pesticides such as fungicides and herbicides (e.g., sec-butylamine derivatives can serve as active ingredients in pesticides).

　　Industrial Field:

　　Chemical intermediate: Used in the synthesis of dyes, pharmaceuticals, surfactants, rubber accelerators, etc. For example, amide compounds produced by reaction with acyl chlorides can serve as pharmaceutical intermediates.

　　Metal corrosion inhibitor: Utilizing its alkalinity and adsorption properties, it forms a protective film on metal surfaces to slow down corrosion (e.g., used in metalworking fluids).

　　Rubber industry: Used as a raw material for rubber vulcanization accelerators to improve the vulcanization properties of rubber.

　　Other Uses:

　　Used in the preparation of corrosion inhibitors, detergent additives, or as a basic catalyst in organic synthesis.

　　Safety and Hazards

　　Toxicity:

　　Moderately toxic; it has strong irritating effects on the skin, eyes, and respiratory tract. Contact may cause burns and allergic reactions.

　　Acute oral toxicity: Rat oral LD₅₀ is approximately 224 mg/kg (classified as toxic). Inhalation of high concentrations of vapor can lead to headaches, nausea, difficulty breathing, and even coma.
