Methyl thieno[3,2-b]thiophene-2-carboxylate(CAS: 98800-10-3)

Methyl thieno[3,2-b]thiophene-2-carboxylate is a crystalline solid with a molecular weight of approximately 228.26 g/mol. It has a low solubility in water but is more soluble in organic solvents like dichloromethane and acetone. The compound is relatively stable under normal conditions but can undergo hydrolysis in the presence of strong acids or bases. It has pKa values around 4.5 to 5.0.

Methyl thieno[3,2-b]thiophene-2-carboxylate is typically synthesized through the condensation of thiophene-2-carboxylic acid with methyl thiophene-2-carboxylate. Commonly used catalysts include oxalyl chloride or N,N'-carbonyldiimidazole (CDI). The reaction is typically performed in dichloromethane and yields around 90% under optimal conditions.

Methyl thieno[3,2-b]thiophene-2-carboxylate is used in the pharmaceutical industry for the synthesis of certain drugs, in the polymer industry for developing advanced materials, and in the semiconductor industry for use in organic light-emitting diodes (OLEDs). It also finds application in sensor technology.

When handling Methyl thieno[3,2-b]thiophene-2-carboxylate, it is essential to wear appropriate personal protective equipment (PPE) including gloves, goggles, and a lab coat. This compound should be stored in a cool, dry place away from direct sunlight and flammable materials. Spills should be cleaned up with appropriate absorbent materials and disposed of according to local hazardous waste regulations. Always refer to a Safety Data Sheet (SDS) for detailed safety information.
