CAS 80-40-0

Ethyl p-toluenesulfonate

Description:

Ethyl p-toluenesulfonate, with the CAS number 80-40-0, is an organic compound that belongs to the class of sulfonates. It is characterized by the presence of a p-toluenesulfonyl group attached to an ethyl group, making it a sulfonate ester. This compound is typically a colorless to pale yellow liquid with a sweet, aromatic odor. Ethyl p-toluenesulfonate is known for its reactivity, particularly in nucleophilic substitution reactions, where it serves as an electrophile due to the presence of the sulfonate group. It is soluble in organic solvents such as ethanol and ether but has limited solubility in water. The compound is often used as a reagent in organic synthesis, particularly in the preparation of various derivatives and in the formation of carbon-carbon bonds. Safety precautions should be taken when handling this substance, as it may cause irritation to the skin and eyes, and appropriate measures should be implemented to avoid inhalation or ingestion.

Ethyl tosylate

CAS: 80-40-0

Ethyl tosylate, or ethyl 4-toluenesulfonate, is the ester derived from the p-toluenesulfonic acid, where the hydrogen atom is substituted by an ethyl group. Ethyl tosylate, and related compounds, such as, methyl-p-toluenesulfonate and 3-butynyl tosylate, are used as alkylating agents in chemical synthesis.
