Tetrahydrothiophene

Product Introduction

Tetrahydrothiophene (CAS 110-01-0), commonly referred to as THT or Thiophane, is a cyclic organosulfur compound with the chemical formula C4H8S. It is a colorless liquid with a strong, characteristic, and highly persistent odor resembling coal gas. Tetrahydrothiophene (CAS 110-01-0) is prized for its extreme chemical and thermal stability. Its most famous application is as a safety warning agent in fuel gases, but its unique properties as a polar, non-protic solvent make it indispensable in advanced chemical synthesis and polymer processing.

Product Selling Points

• Unmatched Odor Persistence: Possesses a distinct, recognizable smell that remains detectable even at extremely low concentrations, ensuring gas leak safety.

• High Chemical Stability: Resistant to many acids and bases, making it a reliable solvent for harsh reaction conditions.

• Excellent Solubility: Miscible with most organic solvents, including alcohols, ethers, and chlorinated hydrocarbons.

• Exceptional Purity (≥ 99.5%): Chemfine ensures a high-grade product with minimal moisture and non-volatile residues.

• Low Soil Adsorption: When used as a gas odorant, it travels well through soil without being filtered out, a critical safety feature for underground pipe leaks.

• Versatile Synthesis Block: A key starting material for producing sulfones and other specialized sulfur-containing industrial chemicals.

Applications

Natural Gas and LPG Odorant The primary global safety additive used to give natural gas a distinctive smell, enabling the rapid detection of leaks in residential and industrial pipelines.

Specialty Industrial Solvent Used as a high-boiling, polar solvent in the production of specialized polymers and in complex organic reactions where stability is required.

Pharmaceutical Intermediate Synthesis Acts as a building block for the synthesis of various active pharmaceutical ingredients (APIs), particularly those containing sulfur heterocycles.

Pesticide and Agrochemical Production Utilized as an intermediate in the manufacturing of high-efficiency insecticides and herbicides to improve bioactivity.

Chemical Catalyst Component Serves as a ligand or additive in certain metal-catalyzed reactions, helping to stabilize the catalyst and control reaction selectivity.

Packaging

Standard industrial packaging options for Tetrahydrothiophene include:

• 200kg tight-head steel drums (Standard export packaging).

• 1000kg IBC tanks for large-scale odorization facilities.

• ISO Tanks for bulk international maritime shipments to gas distribution hubs.

• All packaging is hermetically sealed to prevent odor leakage and is shipped under specialized hazardous material (Class 3) protocols.

Storage

Tetrahydrothiophene is a flammable liquid and is characterized by its intense odor. It must be stored in a cool, dry, and well-ventilated warehouse away from heat, sparks, and open flames. Store in a dedicated area with secondary containment and odor-control systems (such as carbon filters). Keep containers tightly sealed. Store away from strong oxidizing agents and strong acids. Properly stored, it has a shelf life of at least 24 months.
