Detailed Description

Methyl 3-acetamido-4,5-dihydrothiophene-2-carboxylate (CAS 392242-85-2)

This functionalized dihydrothiophene intermediate has the molecular formula C₈H₁₁NO₃S and a calculated molecular weight of 201.24 g/mol. Featuring an acetamido group and a methyl ester moiety on the dihydrothiophene ring, it serves as a key building block for pharmaceutical and fine chemical synthesis.
Key Specifications:
  • CAS No.: 392242-85-2
  • Synonyms: 3-Acetamido-4,5-dihydrothiophene-2-carboxylic acid methyl ester; 2-Thiophenecarboxylic acid, 3-(acetylamino)-4,5-dihydro-, methyl ester
  • Molecular Formula: C₈H₁₁NO₃S
  • Molecular Weight: 201.24 g/mol
  • Purity: ≥98% (custom grades available upon request)
Applications:
This compound is widely used as a precursor in the synthesis of complex heterocyclic molecules, particularly in pharmaceutical R&D. Its dual functional groups enable selective derivatization reactions, supporting the development of dihydrothiophene-based APIs and related derivatives.
Quality & Logistics:
  • Full documentation (COA, HPLC, MSDS) provided for regulatory compliance
  • Flexible packaging options (lab-scale to bulk quantities)
  • Custom synthesis and contract manufacturing services available to meet specific project requirements
