For procurement managers and R&D scientists in the chemical and pharmaceutical sectors, sourcing reliable raw materials is paramount. Among the key organic intermediates, 3,5-Diaminobenzoic Acid (DABA) stands out due to its versatile applications in synthesizing pharmaceuticals and dyes. Understanding its specifications and identifying reputable suppliers is crucial for efficient production and quality control. This guide aims to assist B2B buyers in navigating the process of purchasing high-purity DABA.

Understanding 3,5-Diaminobenzoic Acid (DABA)
3,5-Diaminobenzoic Acid, commonly known as DABA and identified by CAS number 535-87-5, is an aromatic compound featuring both amine and carboxylic acid functional groups. This bifunctionality makes it an exceptionally useful building block in organic synthesis. Its chemical formula is C7H8N2O2, with a molecular weight of approximately 152.15 g/mol. DABA typically appears as a white to gray powder or crystalline solid, with a melting point range of 235-238°C (with decomposition). Its solubility in water is notably high, which can be advantageous in various reaction conditions.

Key Applications in Industry
The primary value of DABA lies in its role as a crucial intermediate. In the pharmaceutical industry, it serves as a raw material for synthesizing various active pharmaceutical ingredients (APIs) and intermediates, contributing to the development of life-saving medications. For instance, it is a precursor in the synthesis of amidotrizoate, a contrast agent. In the dyestuff industry, DABA is utilized in the production of reactive dyes, contributing to vibrant shades and excellent colorfastness. Its structural features also lend themselves to the creation of specialized polymers and other fine chemicals, highlighting its broad utility.

What to Look for When Buying DABA
When purchasing 3,5-Diaminobenzoic Acid, several factors should be considered to ensure you are obtaining a product that meets your exact needs:

  • Purity: DABA is available in various purity levels, typically ranging from 97% to 99% or higher. For demanding applications like pharmaceutical synthesis, a higher purity grade is usually preferred. Always check the Certificate of Analysis (COA) for specific impurity profiles.
  • Physical Appearance: While commonly a white to gray powder, slight variations can occur. Consistent appearance across batches is a good indicator of quality control.
  • Solubility: Its good water solubility is a key characteristic. Confirming its behavior in your intended solvent system is important.
  • Packaging: DABA is typically supplied in various sizes, from grams for R&D to kilograms or drums for industrial production. Ensure the packaging is appropriate for storage and handling, often in sealed aluminum foil bags or fiber cans to maintain integrity.
  • Manufacturer Reputation: Partnering with a reputable chemical supplier or manufacturer, especially one with a strong presence in China, can guarantee quality, competitive pricing, and reliable delivery. Look for suppliers who provide comprehensive product data and certifications.

Finding a Reliable Manufacturer and Supplier
Identifying a trusted 3,5-Diaminobenzoic Acid manufacturer in China is key to securing a consistent supply of high-quality material at a competitive price. When evaluating potential suppliers, consider their experience in chemical manufacturing, their quality control processes, and their ability to provide technical support and documentation, such as MSDS and COA. Many Chinese chemical companies offer free samples, which is an excellent way to assess product quality before committing to a larger purchase. Exploring platforms that list chemical suppliers can help you find manufacturers specializing in pharmaceutical intermediates and organic chemicals.

For businesses seeking to buy 3,5-diaminobenzoic acid, engaging with established suppliers who understand the needs of the pharmaceutical and fine chemical sectors is paramount. These suppliers can offer not only the product itself but also the technical expertise and logistical support necessary for seamless procurement, ensuring your production lines run smoothly.
