1-Butanethiol, commonly referred to by its CAS number 109-79-5, is an organic chemical compound belonging to the thiol family. Its distinctive properties make it a subject of interest for chemical engineers, researchers, and manufacturers. This article provides a detailed look into the chemical profile of 1-Butanethiol, covering its structure, key properties, and industrial relevance.

The chemical structure of 1-Butanethiol consists of a four-carbon chain with a thiol group (-SH) attached to the terminal carbon. Its molecular formula is C4H10S, and its molecular weight is approximately 90.19 g/mol. As a thiol, it exhibits chemical behaviors distinct from alcohols, primarily due to the sulfur atom. It is known for its pungent odor, a characteristic shared by many low-molecular-weight thiols, making it detectable even at very low concentrations.

Physically, 1-Butanethiol is a colorless liquid at room temperature, with a boiling point of 98°C and a melting point of -116°C. Its density is around 0.842 g/mL at 25°C. These properties are crucial for its handling and application in industrial settings. Its solubility in water is limited, but it readily dissolves in many organic solvents, which is advantageous for its use as a solvent or reactant in organic media.

The industrial applications of 1-Butanethiol are varied. It is utilized as an intermediate in the synthesis of various chemicals, including agricultural chemicals and pharmaceuticals. Its strong odor also leads to its use as an odorant for natural gas, providing an early warning for leaks. In the flavor and fragrance industry, it is used in minute quantities to contribute specific notes. The demand for this chemical underscores its importance as a versatile component in modern chemical manufacturing.

Safety is a critical consideration when working with 1-Butanethiol. It is a highly flammable liquid and its vapors can form explosive mixtures with air. Therefore, strict adherence to safety protocols, including proper ventilation, grounding of equipment, and the use of appropriate personal protective equipment (PPE), is essential.
