Description

4-Methylthiophen-2-Amine Hydrochloride is a high-purity organic salt, primarily utilized as a key synthetic intermediate in advanced chemical synthesis. Its value lies in providing a protected amine functionality and a reactive thiophene scaffold, enabling the construction of complex heterocyclic molecules. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, particularly for developing active ingredients and novel chemical entities.

Application

• Pharmaceutical Intermediate: A critical building block in the synthesis of active pharmaceutical ingredients (APIs), especially those containing thiophene or aminothiophene cores.
• Agrochemical Synthesis: Used in the research and production of novel herbicides, fungicides, and insecticides that leverage its heterocyclic structure.
• Material Science Research: Serves as a precursor for functionalized monomers or ligands in the development of conductive polymers, organic semiconductors, and metal-organic frameworks (MOFs).
• Chemical Research & Development: A versatile reagent for constructing complex heterocycles, such as thienopyrimidines or thienodiazepines, in medicinal chemistry programs.
• Dye and Pigment Industry: Acts as an intermediate in the synthesis of specialized dyes and organic pigments where the thiophene ring contributes to color and stability properties.

Quality Control

Our 4-Methylthiophen-2-Amine Hydrochloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and tests for residual solvents and moisture content. We provide a Certificate of Analysis (COA) with every shipment to ensure traceability and compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
