For procurement specialists and research scientists in the chemical and pharmaceutical industries, acquiring high-quality raw materials is a cornerstone of successful operations. When sourcing an intermediate like 4-Chloropicolinic Acid (CAS: 5470-22-4), understanding what constitutes a quality product and a reliable supplier is essential. This guide outlines key aspects to consider when you intend to buy this crucial compound.

The primary characteristic of quality 4-Chloropicolinic Acid is its purity. The provided information indicates a minimum purity of 95% is standard, but for critical applications, especially in pharmaceutical synthesis, higher purities may be required. Always request a Certificate of Analysis (CoA) from the supplier. This document should detail the specific purity of the batch, along with results from analytical tests such as HPLC, GC, NMR, and MS, which confirm the compound's identity and purity profile.

Beyond purity, consider the physical form and stability of the chemical. 4-Chloropicolinic Acid is typically supplied as a white solid. Its stability under normal temperatures and pressures is also important for storage and handling. Suppliers should provide clear storage recommendations, such as keeping the material cold and dry, to maintain its integrity over time.

When evaluating a supplier, particularly when looking for competitive pricing for CAS 5470-22-4 from China manufacturers, their experience and reputation are key indicators. Look for companies with a proven track record in chemical production and a strong commitment to quality control. Factors to investigate include their manufacturing capabilities, their adherence to international quality standards (e.g., ISO certification), and their responsiveness to customer inquiries.

Furthermore, the scope of services offered by a manufacturer can be a deciding factor. If your needs extend beyond standard procurement, consider suppliers who offer custom synthesis or packaging options. As a dedicated manufacturer and supplier, we are equipped to provide not only high-purity 4-Chloropicolinic Acid but also to discuss specific project requirements and offer tailored solutions.

In summary, when buying 4-Chloropicolinic Acid, prioritize obtaining a detailed Certificate of Analysis, understand the storage and handling requirements, and choose a reputable manufacturer with a strong commitment to quality. By taking these steps, you can ensure you are procuring a product that meets your exacting standards and supports your research and production goals effectively.
