Catalog Number - 68524-P21-2503M

cCogent RP Phenyl™ Wide Pore Preparative HPLC Columns are designed for high-capacity purification, preparative separations, and process development involving larger aromatic compounds and structurally related analytes. Manufactured using ultra-high purity silica bonded with a three-carbon linker and terminal Phenyl functionality, this stationary phase is fully double end-capped to minimize secondary interactions and provide highly reproducible chromatographic performance. The 300Å wide pore structure improves accessibility for larger molecules while maintaining the aromatic selectivity characteristic of RP Phenyl™ chemistry.

68524-P21-2503M is packed with 5 µm RP Phenyl™ Wide Pore particles featuring a 300Å pore size in a 21.2 mm ID x 250 mm preparative format. The 5 µm particle size performs well at preparative flow rates while maintaining moderate operating backpressure. The large internal diameter and extended column length provide maximum loading capacity and enhanced chromatographic resolution, making this column ideal for purification, fraction collection, and analytical-to-preparative method scale-up.

The 21.2 mm ID x 250 mm format is particularly well suited for purification of larger positional isomers, tocopherols, flavonoids, polynuclear aromatic hydrocarbons, nitro-aromatic compounds, active pharmaceutical ingredients (APIs), natural products, peptides, and related aromatic compounds. Typical operating flow rates are approximately 15–25 mL/min depending on mobile phase composition, system pressure limitations, and application requirements. A specialized preparative HPLC system capable of supporting these flow rates and sample loads is required.
