Description

2-(6-Methoxynaphthalen-2-Yl)Propanoyl Chloride is a high-purity organic intermediate and a key acyl chloride derivative of naproxen. This compound matters for its critical role as a versatile building block in the synthesis of active pharmaceutical ingredients (APIs) and other fine chemicals. It is primarily needed by pharmaceutical R&D laboratories, fine chemical manufacturers, and agrochemical producers seeking to develop or scale up novel compounds.

Application

• Pharmaceutical Intermediate: A crucial precursor in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs) and other proprietary pharmaceutical compounds.
• API Synthesis: Used as an acylating agent in the production of active pharmaceutical ingredients, particularly in the naproxen chemical family.
• Fine Chemical Manufacturing: Serves as a specialized building block for creating complex organic molecules in research and commercial-scale fine chemical production.
• Agrochemical Research: Employed in the development of novel agrochemicals and plant protection agents due to its reactive propanoyl chloride group.
• Material Science: Potential use in the synthesis of advanced organic materials and functional polymers.
• Academic & Industrial R&D: A valuable reagent for chemical research in academic institutions and corporate R&D centers exploring new synthetic pathways.

Quality Control

Our 2-(6-Methoxynaphthalen-2-Yl)Propanoyl Chloride is manufactured under strict quality management systems. The product undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high chemical purity and consistency. Certificates of Analysis (COA) are provided with each batch, detailing purity, identity, and impurity profiles. We adhere to cGMP standards where applicable to support our clients in regulated industries.

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 and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from strong bases, oxidizers, and sources of ignition.
