3-Methyl-1-butanol (CAS 123-51-3), also known as isoamyl alcohol, is a chemical widely used across various industries. Understanding its chemical properties, stability, and potential hazards is essential for safe handling, storage, and application.

Physically, 3-methyl-1-butanol is a clear, colorless liquid with a distinct, somewhat pungent alcoholic odor. It has a boiling point of approximately 131-132 °C and a melting point of -117 °C. Its density is around 0.809 g/mL at 25 °C. The compound is flammable, with a flash point of about 109.4 °F, classifying it as a flammable liquid. It is soluble in ethanol and ether but only sparingly soluble in water.

Chemically, 3-methyl-1-butanol is a primary alcohol. It is generally stable under recommended storage conditions. However, it is incompatible with strong oxidizing agents, strong acids, acid chlorides, and acid anhydrides, which can lead to hazardous reactions, including potential explosions. Contact with strong oxidizers and hydrogen trisulfide can also cause fires and explosions. Violent reactions can occur with alkaline earth metals, producing flammable hydrogen gas.

Safety is a paramount concern when working with 3-methyl-1-butanol. The vapors can be toxic and irritating to the eyes and upper respiratory tract. Exposure limits, such as NIOSH REL (TWA 100 ppm) and OSHA PEL (TWA 100 ppm), are established to minimize health risks. Appropriate personal protective equipment (PPE), including gloves, eye protection, and respiratory protection when necessary, should be used. Adequate ventilation is crucial in areas where it is handled or stored.

For industrial applications, sourcing 3-methyl-1-butanol from a reputable supplier like NINGBO INNO PHARMCHEM CO.,LTD. ensures that the product meets purity specifications and comes with essential safety documentation, such as a Material Safety Data Sheet (MSDS). This information is vital for implementing safe handling protocols and emergency procedures.

Waste disposal must also be conducted in accordance with all federal, state, and local environmental regulations. Typically, this involves dissolving or mixing the material with a combustible solvent and burning it in a chemical incinerator equipped with an afterburner and scrubber.

By understanding and respecting the chemical properties and hazards of 3-methyl-1-butanol, industries can safely and effectively utilize this valuable chemical intermediate in their processes, ensuring both operational efficiency and workplace safety.
