1-Iodobutane CAS 542-69-8

1. 1-Iodobutane CAS 542-69-8 is widely used as a versatile alkylating agent in organic synthesis for introducing the butyl group into target molecules .
2. 1-Iodobutane serves as an important pharmaceutical intermediate for producing antiseptics, disinfectants, and polarizing films for liquid crystal display (LCD) chemicals .
3. 1-Iodobutane is utilized as an analytical reagent, solvent, and building block for synthesizing various organic compounds including S-alkylated triazole derivatives .

1. Store 1-Iodobutane CAS 542-69-8 in a tightly sealed container under inert gas in a cool, dark place below 15°C, as 1-Iodobutane is light sensitive and air sensitive .
2. Keep 1-Iodobutane strictly away from strong oxidizing agents, strong bases, and sources of ignition, with storage temperatures not exceeding 30°C.
3. Handle 1-Iodobutane using appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and in a fume hood to avoid breathing vapors and contact with skin and eyes .

1. Isolate the spill area, eliminate all ignition sources, and contain liquid 1-Iodobutane CAS 542-69-8 using dry inert absorbent material like sand or activated carbon, preventing entry into drains or waterways .
2. Collect absorbed 1-Iodobutane using non-sparking, explosion-proof tools into sealed, labeled containers for disposal according to hazardous material regulations .
3. Personnel cleaning 1-Iodobutane spills must wear full protective equipment including self-contained breathing apparatus, as vapors may accumulate to form explosive concentrations and 1-Iodobutane is classified for transport (UN 1993, Hazard Class 3, PG III) .

1. 1-Iodobutane CAS 542-69-8 is a flammable liquid and vapor (H226) with a flash point of 33-49°C, causing skin irritation (H315), serious eye irritation (H319), and may cause respiratory irritation (H335) .
2. 1-Iodobutane is harmful if swallowed, harmful if inhaled (H332), and toxic in contact with skin (LC50 rat inhalation: 6100 mg/m³/4h) .
3. Combustion of 1-Iodobutane produces toxic fumes including carbon oxides and hydrogen iodide ; 1-Iodobutane is insoluble in water with a molecular weight of 184.02 .
