Alphabond Phenyl

Aromatic-Selective Reversed-Phase Column for Enhanced π–π Interactions

Alphabond Phenyl is a reversed-phase HPLC column based on fully porous, high-purity silica modified with phenyl functional groups. This phase offers unique selectivity for aromatic and conjugated compounds through π–π interactions, providing an alternative to traditional alkyl-bonded columns such as C18 or C8. Alphabond Phenyl delivers moderate hydrophobicity and is ideal for separating structurally similar aromatic analytes in pharmaceutical, food, and environmental applications.

Alphabond Phenyl offers distinct reversed-phase behavior for aromatic-rich compounds – a useful option when standard alkyl phases are not selective enough.

Good alternative to PharmaBOND Phenyl (Princeton Chromatography INC.) and µBondapak Phenyl (Waters™).
