CAS 75-66-1

tert-Butyl mercaptan

Description:

Tert-butyl mercaptan, also known as tert-butyl thiol, is an organic compound with the chemical formula C4H10S and a CAS number of 75-66-1. It is characterized by a strong, unpleasant odor, often described as similar to that of rotten cabbage or garlic, which makes it useful as an odorant in natural gas to detect leaks. This compound is a colorless liquid at room temperature and is soluble in organic solvents but has limited solubility in water. Tert-butyl mercaptan is known for its reactivity, particularly due to the presence of the thiol (-SH) functional group, which can participate in various chemical reactions, including oxidation and substitution reactions. It is used in the synthesis of other chemicals, as a flavoring agent in the food industry, and in the production of certain pharmaceuticals. Safety precautions are necessary when handling this compound, as it can be irritating to the skin, eyes, and respiratory system. Proper storage in a cool, well-ventilated area is also recommended to minimize exposure.

2-Methyl-2-propanethiol

CAS: 75-66-1

2-Methyl-2-propanethiol is an electron acceptor and a reagent that can be used for the synthesis of organic compounds. It is soluble in polar solvents, but insoluble in nonpolar solvents. 2-Methyl-2-propanethiol has been shown to react with thiols at concentrations below its optimum concentration. The reaction mechanism is believed to involve adsorption and intramolecular hydrogen transfer. The adsorption process occurs on the surface of the substrate and the intramolecular hydrogen transfer occurs through an intermolecular hydrogen bond with the substrate's hydroxyl group or disulfide bond. When 2-methyl-2-propanethiol reacts with a thiol, it forms a mercaptan group called p2 that contains two substituents, one on each carbon atom. This reaction produces a disulfide bond as well as an electrochemical detector signal known as "activated."
