Description

Propanamide, n-(3-Cyano-4-Ethyl-5-Methyl-2-Thienyl)- (9Ci) is a specialized organic compound featuring a thiophene core substituted with cyano, ethyl, and methyl groups, and functionalized with a propanamide side chain. This unique molecular architecture makes it a valuable high-purity intermediate for advanced chemical synthesis, particularly in the development of novel active pharmaceutical ingredients (APIs) and functional materials. It is primarily sought by pharmaceutical R&D teams and fine chemical manufacturers engaged in creating complex heterocyclic compounds.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders or possessing specific receptor activity.
• Agrochemical Research: Used in the development of new-generation herbicides, fungicides, or insecticides, leveraging its heterocyclic structure for bioactivity.
• Material Science: Serves as a precursor for organic semiconductors, conductive polymers, or advanced dyes due to its electron-rich thiophene and cyano functionalities.
• Chemical Synthesis: Employed in academic and industrial research as a versatile scaffold for creating libraries of complex molecules for screening and discovery.
• Ligand & Catalyst Development: The functional groups present make it a candidate for designing novel ligands used in catalytic processes or metal-organic frameworks (MOFs).

Quality Control

Our production of Propanamide, n-(3-Cyano-4-Ethyl-5-Methyl-2-Thienyl)- (9Ci) adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity for sensitive synthetic applications. All materials undergo rigorous analytical testing, including HPLC for purity and identity confirmation via NMR and IR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing purity, residual solvents, and specific impurities is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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. Keep away from incompatible materials.
