Description

2-Thiophenecarboxamide, 5-Chloro-n-Methyl- CAS NO 97799-98-9 is a high-purity, functionalized thiophene derivative serving as a critical building block in advanced organic synthesis. This compound matters for its role as a versatile intermediate in the development of novel active pharmaceutical ingredients (APIs) and specialty agrochemicals. It is primarily needed by research and development chemists and process scale-up teams within the pharmaceutical, agrochemical, and material science industries seeking to incorporate halogenated heterocyclic motifs into their molecular architectures.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders and anti-infective agents.
• Agrochemical Synthesis: Serves as a core scaffold for developing new-generation herbicides, fungicides, and insecticides with improved efficacy.
• Material Science Research: Used in the development of organic semiconductors, conductive polymers, and non-linear optical (NLO) materials due to the thiophene backbone.
• Chemical Biology Probes: Employed in medicinal chemistry for structure-activity relationship (SAR) studies and as a tagged molecule in biochemical assays.
• Custom Synthesis & Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for custom synthesis projects requiring specific halogenated heterocycles.
