For any B2B procurement professional or research scientist, the specifications of a chemical intermediate are fundamental to ensuring successful experimental outcomes and product quality. 4-Iodo-1-methyl-1H-pyrazole, with its CAS number 39806-90-1, is no exception. Understanding its key characteristics, such as appearance, melting point, and purity, is crucial before you decide to buy.

The typical appearance of 4-Iodo-1-methyl-1H-pyrazole is a white solid. This physical characteristic is an initial indicator of product quality. Any deviation from this expected appearance, such as discoloration or the presence of foreign matter, might suggest contamination or degradation, necessitating further investigation before purchase.

The melting point of 4-Iodo-1-methyl-1H-pyrazole is generally reported in the range of 61-67°C, with some sources citing 64-65°C. A narrow melting point range is often indicative of high purity. When you inquire about the price from a manufacturer, ask for their reported melting point range as part of the product's technical data sheet. This detail is vital for researchers who rely on precise thermal properties for their reactions or formulation development.

Purity is perhaps the most critical specification. For 4-Iodo-1-methyl-1H-pyrazole, purities of 97% or higher are commonly sought after, particularly for pharmaceutical applications. High purity ensures that the intermediate will perform as expected in complex synthetic sequences, minimizing side products and maximizing the yield of your desired compound. When you are ready to purchase, always request a Certificate of Analysis (CoA) that clearly states the purity level and the analytical method used (e.g., GC or HPLC).

Working with a reputable supplier means having access to this detailed information upfront. A dedicated manufacturer will also provide guidance on proper storage conditions, such as keeping the product in a dark, dry place at room temperature, to maintain its integrity. This commitment to quality ensures that when you receive your order of 4-Iodo-1-methyl-1H-pyrazole, it meets the high standards required for your critical applications.
