Sourcing 3,4-Dihydroxybenzoic Acid: A Guide for Buyers

For procurement managers and R&D scientists in the chemical and pharmaceutical industries, sourcing high-quality raw materials is paramount. One such essential compound is 3,4-Dihydroxybenzoic Acid, commonly known by its CAS number 99-50-3. This versatile chemical intermediate plays a significant role in various sectors, most notably as a key component in the synthesis of pharmaceuticals and dyestuffs. Understanding its properties and how to procure it effectively can streamline your supply chain and R&D efforts.

What is 3,4-Dihydroxybenzoic Acid?

3,4-Dihydroxybenzoic Acid, also referred to as Protocatechuic Acid, is a phenolic acid. It is characterized by its distinct chemical structure which makes it a valuable intermediate in organic synthesis. The primary uses of this compound are as an intermediate for dyestuffs and medicines, and it also serves as an analytical reagent, particularly in the determination of iron. Its consistent quality is crucial for its end applications.

Key Specifications for Procurement

When looking to buy 3,4-Dihydroxybenzoic Acid, it's important to focus on key specifications that guarantee its suitability for your intended use. Reputable manufacturers and suppliers will provide detailed information on:

  • Appearance: Typically described as a Light-Yellow or White-like Powder.
  • Assay (Purity): High purity, often ≥99.0% (by HPLC), is essential for pharmaceutical applications.
  • Loss on Drying: Typically kept to a minimum, often ≤1.0%.
  • Melting Point: A narrow range, such as 202.0-207.0℃, indicates good purity.

Proper packaging, such as 25KG drums, and adherence to storage guidelines (dry, ventilated, away from sunshine and moisture) are also critical for maintaining product integrity. For buyers seeking to purchase 3,4-Dihydroxybenzoic Acid, verifying these specifications with a reliable supplier is the first step.

Finding a Reliable Manufacturer and Supplier

The global market offers numerous options for sourcing chemical intermediates. However, for critical applications like pharmaceutical synthesis, partnering with a dependable manufacturer is key. Look for suppliers who can provide:

  • Consistent product quality and purity.
  • Competitive pricing, especially for bulk orders.
  • Flexible packaging and delivery options.
  • Excellent customer support and technical assistance.
  • A strong track record in the chemical supply chain.

When searching for a 3,4-Dihydroxybenzoic Acid supplier, consider those based in major chemical manufacturing hubs like China, known for their robust production capabilities and export networks. Engaging with a manufacturer that understands the stringent requirements of the pharmaceutical sector ensures you receive a product that meets international standards. This is crucial if you are looking to buy CAS 99-50-3 for your formulation needs.

Conclusion

Securing a consistent and high-quality supply of 3,4-Dihydroxybenzoic Acid is vital for the success of many chemical and pharmaceutical manufacturing processes. By focusing on detailed specifications, understanding product applications, and partnering with reputable manufacturers and suppliers, businesses can ensure they are obtaining the best possible raw materials. If you are seeking a reliable source for 3,4-Dihydroxybenzoic Acid, inquire with experienced chemical providers to discuss your specific requirements and secure competitive pricing.
