For professionals in the chemical, electronics, and advanced materials industries, the consistent and cost-effective sourcing of specialty chemicals is a constant challenge. 2-(4-Aminophenyl)-1H-benzimidazol-5-amine (CAS 7621-86-5), also known by its acronym APBIA, is a highly sought-after intermediate. Its primary utility as a monomer in the synthesis of high-performance polymers like polyimides, along with its potential in electronic materials and as a pharmaceutical intermediate, underscores its importance. This guide is designed for B2B buyers to effectively navigate the market, understand quality parameters, and secure competitive pricing from trusted manufacturers and suppliers.

When looking to buy 2-(4-Aminophenyl)-1H-benzimidazol-5-amine, understanding its specifications is the first step. Key quality indicators include purity (typically >99%), appearance (e.g., pale beige to pale brown powder), molecular formula (C13H12N4), and molecular weight (224.26 g/mol). Reputable suppliers will readily provide Certificates of Analysis (CoA) detailing these specifications, ensuring the material meets your stringent requirements for applications such as creating advanced polyimide resins with excellent thermal stability and melt fluidity, or as a component in organic-inorganic hybrid proton exchange membranes.

The global supply chain for chemicals like APBIA is robust, with many reliable manufacturers located in China. When evaluating potential suppliers, consider factors such as production capacity, quality control measures, and the ability to provide consistent batches. A good manufacturer will not only offer competitive price points but also demonstrate a commitment to ethical business practices and regulatory compliance. For procurement managers, establishing a relationship with a dependable supplier is crucial for uninterrupted production and research continuity.

Understanding the typical price range for 2-(4-Aminophenyl)-1H-benzimidazol-5-amine requires looking at various suppliers and their offerings. Factors influencing price include order volume, purity level, and current market demand. Engaging directly with manufacturers or authorized distributors is the most effective way to obtain accurate quotes. For those planning large-scale industrial use or significant research projects, inquiring about bulk discounts and long-term supply agreements is advisable. Ensure your chosen supplier can handle your required quantities, whether it’s kilograms for R&D or metric tons for industrial production.

Furthermore, a comprehensive supplier evaluation should include their responsiveness to inquiries, the clarity of their communication regarding lead times and shipping, and their after-sales support. If you are specifically looking for 2-(4-aminophenyl)-1h-benzimidazol-5-amine for polyimide synthesis, confirm that the supplier has experience in providing materials for this specific application and can provide technical guidance if needed.

In summary, sourcing 2-(4-Aminophenyl)-1H-benzimidazol-5-amine (CAS 7621-86-5) effectively involves a diligent approach to supplier selection. Focus on purity, competitive pricing, and reliability.
