In the realm of fine chemicals and synthesis intermediates, understanding and verifying product specifications is fundamental to ensuring successful outcomes in research and manufacturing. 2-Amino-3,5-dichloropyridine (CAS 4214-74-8) is no exception. For professionals in the pharmaceutical, agrochemical, and materials science sectors, sourcing this compound with the correct specifications guarantees predictable reaction performance, product quality, and compliance.

Key Quality Parameters for 2-Amino-3,5-dichloropyridine

When you decide to buy 2-Amino-3,5-dichloropyridine, paying close attention to several key quality parameters is essential. These specifications are typically provided by manufacturers and are critical for assessing the suitability of the product for your intended application:

  • Assay/Purity: This is perhaps the most crucial specification. For 2-Amino-3,5-dichloropyridine, a high purity level, often indicated as ≥99.0% (by GC or HPLC), is generally required for sensitive synthesis reactions. A higher assay ensures fewer unwanted side reactions and byproducts.
  • Appearance: The visual characteristic of the compound is important. This intermediate is typically described as a white crystal. Any significant deviation in color or form might indicate contamination or degradation.
  • Melting Point: The melting point range provides an indication of purity. For 2-Amino-3,5-dichloropyridine, a tight melting point range, such as 80-84°C, suggests high purity. A broad or lower melting point can signal the presence of impurities.
  • Loss on Drying (LOD): This specification measures the amount of volatile matter (usually moisture) present in the sample. A low LOD (e.g., ≤0.5%) is desirable to ensure the compound's stability and accurate weighing for reactions.
  • CAS Number and Molecular Information: While not a quality parameter in itself, confirming the correct CAS Number (4214-74-8), molecular formula (C5H4Cl2N2), and molecular weight (approx. 163 g/mol) is fundamental for accurate identification and process calculation.

Ensuring Reliable Sourcing

Procurement managers and R&D scientists should always request detailed specification sheets and Certificates of Analysis (CoA) from potential suppliers. Working with a manufacturer that emphasizes stringent quality control and offers transparent documentation is paramount. If you are looking for a reliable supplier of 2-Amino-3,5-dichloropyridine with guaranteed high purity and competitive pricing, consider established chemical manufacturers in China. They are equipped to meet the rigorous demands of the global chemical market and can provide the necessary quality assurance for your synthesis projects.
