For B2B procurement managers and R&D scientists, sourcing reliable chemical intermediates is paramount to successful product development and manufacturing. One such crucial intermediate is 4-Fluorophthalic Anhydride (CAS 319-03-9). Understanding its properties, applications, and the best strategies for procurement can significantly impact your supply chain efficiency and product quality. This article aims to provide a comprehensive guide for buyers looking to purchase high-purity 4-Fluorophthalic Anhydride.

Understanding 4-Fluorophthalic Anhydride (CAS 319-03-9)

4-Fluorophthalic Anhydride is a derivative of phthalic anhydride, characterized by a fluorine atom substituted on the aromatic ring. This fluorine substituent often imparts unique chemical and physical properties, making it a valuable building block in organic synthesis. It is typically supplied as a white crystalline powder with a high purity, often exceeding 99.5%. Its molecular formula is C8H3FO3 and its molecular weight is approximately 166.11 g/mol. Key physical properties include a melting point around 74-75°C. Its reactivity makes it suitable for a wide range of chemical transformations.

Key Applications in Various Industries

The versatility of 4-Fluorophthalic Anhydride makes it a sought-after intermediate across multiple sectors:

  • Pharmaceuticals: It serves as a critical starting material or intermediate in the synthesis of various Active Pharmaceutical Ingredients (APIs) and complex drug molecules. The fluorine atom can influence a drug's metabolic stability, lipophilicity, and binding affinity.
  • Agrochemicals: This compound is used in the development of advanced pesticides, herbicides, and fungicides, contributing to crop protection and yield enhancement.
  • Polymers and Materials Science: 4-Fluorophthalic Anhydride can be incorporated into the synthesis of specialty polymers, including polyesters and polyimides, to impart enhanced thermal stability, flame retardancy, or unique optical properties.
  • Fine Chemicals: It acts as a versatile synthon for a broad spectrum of fine chemical products, catering to niche industrial demands.

Strategic Sourcing: Finding a Reliable Manufacturer and Supplier

When looking to buy 4-Fluorophthalic Anhydride, selecting a dependable manufacturer and supplier is crucial. Buyers should prioritize suppliers who can guarantee consistent quality, timely delivery, and competitive pricing. For businesses operating in regions like China, identifying established manufacturers with robust quality control systems and export experience is key. A reputable supplier will readily provide technical data sheets (TDS), certificates of analysis (CoA), and a clear pricing structure. Inquiries about bulk pricing, minimum order quantities (MOQs), and payment terms are standard practice when securing your supply.
