Description

Ethanone, 2-Chloro-1-(5-Methyl-2-Thienyl)- (9Ci) is a specialized organic compound featuring a chlorinated acetyl group attached to a methyl-substituted thiophene ring. This unique molecular architecture makes it a valuable high-purity intermediate for advanced chemical synthesis. It is primarily sought by pharmaceutical and agrochemical R&D sectors for the development of novel active ingredients and fine chemicals.

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 Synthesis: Used in the research and development of new herbicides, fungicides, or insecticides, leveraging the reactivity of the thiophene and carbonyl groups.
• Material Science Research: Serves as a precursor for functionalized polymers or organic electronic materials due to the conjugated thiophene system.
• Chemical Research & Development: Employed in academic and industrial labs for methodological studies in heterocyclic and organochlorine chemistry.
• Fine Chemical Production: Acts as a critical intermediate in the multi-step synthesis of complex, high-value specialty chemicals.

Quality Control

We maintain a strict quality management system to ensure batch-to-batch consistency and high purity. Our products undergo rigorous quality testing, including advanced chromatographic and spectroscopic methods, to ensure compliance with industry and research-grade standards. Comprehensive Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request for every shipment.

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.
