Propyl 4-hydroxybenzoate or propylparaben is a very useful compound in cosmetics and often used as a preservative in lotions and creams. The reverse-phase column Legacy L1 was used to retain propyl 4-hydroxybenzoate. Comparisons to Phenomenex columns are available upon request.

SIELC's family of Legacy columns is based on the United States Pharmacopeia's (USP) published chromatographic methods and procedures. Numerous brands have columns used in USP reference standards and methods. USP has created various designations to group together columns with similar types of packing and properties in the solid phase. SIELC's Legacy columns adhere to these strict requirements and properties, allowing you to easily replace older columns that are no longer available without needing to significantly modify your method or SOPs.
