Description

Benzoyl Chloride, 5-Ethyl-2-Hydroxy- (9Ci) is a specialized aromatic acid chloride derivative, serving as a critical building block in advanced organic synthesis. Its value lies in its dual functional groups, which enable precise acylation and subsequent functionalization reactions, making it indispensable for creating complex molecular architectures. This high-purity intermediate is primarily needed by R&D laboratories and production facilities in the pharmaceutical, agrochemical, and fine chemical industries for developing active ingredients and novel compounds.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a benzoyl-protected phenolic moiety.
• Agrochemical Synthesis: Used in the manufacture of herbicides, fungicides, and plant growth regulators where its structure contributes to biological activity.
• Fine Chemical Production: Essential for constructing complex molecules in perfumery, dye, and specialty polymer research.
• Academic & Industrial R&D: Serves as a versatile reagent for method development and exploring new chemical entities in organic chemistry.
• Material Science: Potential monomer or cross-linking agent in the development of specialty resins and advanced polymeric materials.

Quality Control

Our Benzoyl Chloride, 5-Ethyl-2-Hydroxy- (9Ci) is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, IR for identification, and Karl Fischer titration for moisture content, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) with detailed specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent hydrolysis and degradation. Keep away from strong bases and oxidizing agents.
