(+)-2-Butanol

Description:

(+)-2-Butanol, also known as (S)-2-butanol, is a chiral alcohol with the molecular formula C4H10O. It is characterized by its hydroxyl (-OH) functional group attached to the second carbon of a four-carbon butane chain. This compound is a colorless liquid at room temperature and has a characteristic alcoholic odor. It is soluble in water due to the presence of the hydroxyl group, which allows for hydrogen bonding. The compound exhibits optical activity, meaning it can rotate plane-polarized light due to its chiral nature. (+)-2-Butanol is commonly used as a solvent in various chemical reactions and industrial processes, as well as in the synthesis of other organic compounds. Its boiling point is relatively moderate, and it has a low vapor pressure, making it less volatile compared to smaller alcohols. Safety considerations include flammability and potential health effects upon inhalation or skin contact, necessitating appropriate handling and storage measures.

(S)-(+)-2-Butanol

Controlled Product

CAS: 4221-99-2

The compound (S)-(+)-2-Butanol is a chiral molecule that is used in the synthesis of benzodiazepines. The (+) enantiomer of 2-butanol has been shown to bind to the GABA receptor and has an inhibitory effect on benzodiazepine binding. It is also a competitive inhibitor for the enzyme dehydrogenase, which converts 2-butanol to acetaldehyde. The (-) enantiomer of 2-butanol does not have any effect on the GABA receptor or dehydrogenase activity. This means that the (+) enantiomer is responsible for the activation energy and stereoselectivity of this reaction. The activation energy for this reaction can be calculated by measuring the amount of heat released during the reaction. This process can be done through vibrational spectroscopy or by running control experiments with a known concentration of reactants and products. There are many ways to determine whether this reaction follows an elimination or dehydration mechanism,
