TRIMETHYLENE GLYCOL DITOSYLATE - Introduction

1,3-Propanediol di-p-toluenesulfonate is an organic compound with the chemical formula C14H18O6S2. It is a white solid which is soluble in organic solvents such as methanol, ethanol and dimethylformamide.

This compound is widely used in organic synthesis. It can be used as an intermediate in the synthesis of ethynyl and sulfating reagents. It is also an effective alcohol protecting group and can be used for hydroxyl protection reactions in organic synthesis. In addition, it can also be used as a reaction solvent or as a component of the ionic liquid.

The method for preparing 1,3-Propanediol di-p-toluenesulfonate is usually obtained by reacting p-methanesulfonic acid and 1,3-propanediol under acid-catalyzed conditions. The reaction conditions are generally at elevated temperatures, such as 100-120°C, and generally longer reaction times.

In terms of safety, the compound is generally stable and safe under normal conditions of use. However, it can cause irritation and allergic reactions, so use appropriate precautions, such as wearing respirators, chemical protective clothing and chemical safety goggles. At the same time, contact with skin, eyes and respiratory tract should be avoided to prevent discomfort or injury. In case of ingestion or contact, immediate care and consultation with a doctor should be undertaken.
