(5-Chloro-2-thienyl)methanol(CAS: 74168-69-7)

(5-Chloro-2-thienyl)methanol (CAS: 74168-69-7) is a crystalline solid with a molecular weight of approximately 189.02 g/mol. It has a low solubility in water but is more soluble in organic solvents like ethanol and acetone. Chemically, it is reactive towards nucleophiles and can participate in electrophilic substitution reactions due to the presence of the thienyl ring and chlorine substituent.

(5-Chloro-2-thienyl)methanol is typically synthesized via a multistep process involving the reaction of 2-chlorothiophene with methanol in the presence of a suitable base like sodium methoxide. The reaction is carried out in an aprotic solvent to avoid side reactions. The yield is usually around 60-70%, and the product is purified by recrystallization.

(5-Chloro-2-thienyl)methanol finds applications in the pharmaceutical industry as a precursor for synthesizing various drug molecules. It is also used in the polymer industry for the development of advanced materials and in the sensor and semiconductor industries for specific functional groups that can enhance material properties.

When handling (5-Chloro-2-thienyl)methanol (CAS: 74168-69-7), it is essential to wear appropriate personal protective equipment (PPE) including gloves, goggles, and a lab coat. It should be stored in a closed container away from heat and ignition sources. In case of a spill, use appropriate spill cleanup procedures and ensure proper disposal. Always refer to the safety data sheet (SDS) for detailed information on safe handling and emergency procedures.
