    Though this is a purification blog I do, from time to time, like to address synthetic chemistry experimentation findings in the desire to assist you with your reactions, as this is the front-end of your synthesis workflow. So, in this post, I report on some findings of the effect of reaction temperature on the synthesis of an amide, 2-amino-N-benzylbenzamide, a potential antibacterial compound[1].

    Flash chromatography is a purification technique used by chemists to isolate their targeted compound from by-products and impurities. Because the reaction mixture (or natural product extract) may have its best solubility in a solvent that is chromatographically “stronger” than the mobile phase, liquid sample loading can be problematic causing early-eluting, broad peaks which can reduce purification efficacy and product purity. In those cases, a technique called dry loading is a better alternative.
