1Propanesulfonate

1-Propanesulfonate is an organosulfur compound with the chemical formula CH3CH2CH2SO3-. It is a salt derived from propane sulfonic acid. The structure consists of a three-carbon propyl chain attached to a sulfonate group (-SO3-). It is a polar molecule due to the presence of the sulfonate group.

The compound can exist as a sodium salt, commonly known as sodium 1-propanesulfonate, with the formula CH3CH2CH2SO3Na. Sodium 1-propanesulfonate is a white crystalline solid that is soluble in water. It is often used in electroplating baths, particularly in the plating of copper, as a brightener and leveling agent. Its presence helps to produce smooth, lustrous deposits.

1-Propanesulfonate and its salts can also find applications in other areas, such as surfactants and as components in certain chemical synthesis processes. The specific properties and uses depend on the counterion associated with the sulfonate group. As a sulfonate, it is a relatively stable and non-volatile compound.
