Product Technical Details

Product Overview

1-Butanethiol, also widely recognized in the chemical industry as Butyl Mercaptan, is a primary organosulfur compound characterized by its distinct thiol functional group. This colorless transparent liquid serves as a critical building block in various complex organic synthesis pathways. Our manufacturing process ensures high industrial purity, making it an ideal choice for pharmaceutical research, agrochemical production, and specialized chemical formulations. As a leading global manufacturer, we prioritize consistency and quality in every batch produced.

Chemical Properties and Characteristics

This sulfur-containing compound exhibits specific physical properties that define its handling and application potential. With a molecular formula of C4H10S and a molecular weight of approximately 90.19 g/mol, it possesses a boiling point of 98°C and a melting point of -116°C. The density stands at 0.842 g/cm³, and it features a refractive index of 1.443. Due to the reactive nature of the sulfhydryl group, 1-Butanethiol acts as a potent nucleophile in substitution reactions, facilitating the creation of thioethers and other sulfur-bridged structures essential in medicinal chemistry.

Industrial Applications

The versatility of 1-Butanethiol extends across multiple sectors within the chemical value chain. Primarily, it is utilized as a key intermediate in the synthesis of pharmaceutical active ingredients, where sulfur incorporation is required for biological activity. Additionally, it finds application in the agrochemical industry for developing specific pesticides and herbicides. Beyond synthesis, it is sometimes employed in odorant formulations for gas leak detection due to its strong scent, although our high-purity grade is specifically optimized for synthetic applications rather than direct consumer use. The compound's reactivity allows for efficient integration into continuous flow chemistry and batch processing environments.
