Overview of 1-Butanethiol

1-Butanethiol, also known as Butyl Mercaptan or N-Butyl Mercaptan, is a strong sulfur-based organic compound recognised for its sharp, skunk-like odour. It is a clear to pale-yellow liquid widely used in industrial applications, research laboratories, fuel odorants, and organic chemical synthesis.

Due to its high odour strength, it is effective in trace-level applications, especially in gas warning agents and chemical intermediates. ChemicalBull supplies high-purity 1-Butanethiol suitable for industrial, research, and speciality formulation requirements.

You may also like: Tert-Butyl Mercaptan, Methanethiol, Ethanethiol, Isobutyl Mercaptan, and 1-Pentanethiol for thiol and sulfur compound applications.

Applications of 1-Butanethiol

Industrial Applications

Used as an intermediate in chemical synthesis.
Applied in fuel additives and gas odorization systems as an early warning compound.
Valuable in polymer research and sulfur-based reactions.

Research & Laboratory Use

Used for mechanism studies and organic reaction development.
Acts as a precursor in the preparation of thiols and sulfide derivatives.

Odorant & Safety Systems

Suitable for gas leak detection, due to extremely strong odour even in low ppm levels.

Safety & Handling Guidelines

Always wear gloves, goggles, and lab-grade protective equipment while handling.
Avoid direct inhalation — fumes are strong and irritating.
