Polyamide powder (100-200 mesh) is a specialty adsorbent used in column chromatography for the separation and purification of organic compounds, particularly those with polar functional groups. It offers selective adsorption based on hydrogen bonding and dipole interactions, making it ideal for isolating phenols, amines, and other polar molecules from non-polar impurities. This niche material is valued in pharmaceutical, natural product, and fine chemical synthesis for its ability to achieve high-resolution separations without the need for derivatization. Unlike general polyamide polymers used in fibers or plastics, this form is specifically processed for chromatographic applications, providing consistent particle size for efficient column packing and flow.
