3-甲基苯并[B]噻吩-2-羰醛 (CAS No.22053-74-3)

Product Name:3-METHYLBENZO[B]THIOPHENE-2-CARBOXALDEHYDE

English Name:3-METHYLBENZO[B]THIOPHENE-2-CARBOXALDEHYDE

CAS No.:22053-74-3

Aliases:3-methylbenzo[b]thiophene-2-carbaldehyde, 3-methyl-2-formylbenzothiophene, 3-methylbenzothiophene-2-carboxaldehyde

Molecular Formula:C10H8OS

Physical Properties:This product appears as a light yellow to light brown solid or crystalline powder with a characteristic aromatic odor. Melting point is approximately 72-76°C, boiling point is about 310°C at atmospheric pressure, relative density is approximately 1.2 g/cm³, and flash point is about 140°C. It is readily soluble in organic solvents such as ethanol, diethyl ether, dichloromethane, and ethyl acetate, but insoluble in water. It is stable in air and sensitive to light; store in a cool, dark place in an airtight container.

Uses:This compound is an important organic synthesis intermediate, mainly used for synthesizing benzo[b]thiophene-containing pharmaceutical molecules, such as anti-inflammatory, analgesic, and antitumor agents. It is also applicable in the synthesis of agrochemicals, dyes, and functional materials. The aldehyde group can participate in condensation, reduction, and oxidation reactions, making it a valuable building block for constructing complex heterocyclic compounds.
