1-cyclohexylethyl 2-butenoate(CAS#68039-69-0)

Introduction

6,7,8,8α-Tetrahydro-2,5,5,8α-tetramethyl-5H-1-benzopyran, also known as THP (Tetrahydropyranyl). Properties:- THP is a colorless liquid with oily characteristics.- It has a distinct benzopyran structure, serving as a protecting group in chemical reactions.- THP has high thermal stability and solubility, and it can dissolve in many solvents.Uses:- THP is widely used in organic synthesis as a protecting group. It can protect active groups in reactions from interference or damage, while being easily removable when needed.- THP can be used in the synthesis of various compounds, such as alcohols, ethers, and ketones, for protection and as synthetic intermediates.Preparation:- THP is commonly prepared by the reaction of an alcohol with 4-methyl-2,5-dihydrofuran. Common reaction conditions include acidic or basic environments, with catalysts such as dilute sulfuric acid or copper chloride.Safety Information:- THP is generally considered relatively safe, but it is still an organic solvent and should be handled with care.- Avoid inhalation, ingestion, and contact with skin and eyes when handling THP.- Use appropriate personal protective equipment, such as gloves, safety goggles, and protective clothing, when working with THP.- Ensure good ventilation during storage and handling, and avoid contact with oxidizers and strong acids or bases.- Dispose of THP waste according to local regulations. …
