O-Ethyl butanethioate(CAS: 20807-99-2)

O-Ethyl butanethioate (CAS: 20807-99-2) is a liquid with a characteristic odor. Its molecular weight is approximately 154.23 g/mol. It is slightly soluble in water but miscible with most organic solvents. The compound is mildly reactive and should be stored away from strong oxidizers and heat sources to prevent degradation.

O-Ethyl butanethioate can be synthesized via the reaction of ethyl bromide with butanethiol in the presence of a base such as sodium hydroxide. The reaction yields a mixture of isomers, but the major product is the O-ethyl isomer. The yield is typically around 80-85%. This method provides a straightforward route to the compound.

O-Ethyl butanethioate (CAS: 20807-99-2) is primarily used in the pharmaceutical industry as an intermediate in the synthesis of certain drugs. It is also used in the production of fragrances, as a solvent, and in the development of chemical sensors for detecting thiols in various applications.

When handling O-Ethyl butanethioate (CAS: 20807-99-2), it is essential to wear appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. Operations should be performed in a well-ventilated area or a fume hood to minimize inhalation risks. Spills should be cleaned up immediately, and proper waste disposal procedures should be followed. Always consult the Safety Data Sheet (SDS) for detailed handling and safety information.
