Ultra-low Bleed Phenyl Phase with Enhanced Phenyl Selectivity
Phenyl-based reversed-phases were one of the first alternatives to C18 selectivity. Our Ascentis Phenyl has been improved to offer exceptional phase stability and enhanced phenyl retention. Ascentis Phenyl offers versatility by also operating in the HILIC mode.

Ordering Information for Ascentis Phenyl HPLC columns
Use
Phenyl phases are π-basic (electron donating) and are similar in overall retention to alkyl and EPG phases for easy column screening. The alternate selectivity of phenyl phases is often explained by the π-π interactions available through the phenyl ring. Compounds that appear to exhibit differential selectivity on the phenyl phase include:
Notes
what is the use of phenyl ?
The phenyl is used in the hair care formulations and cosmetics.
First off, if it has Phenyl in it, it is a poison
it has phenyl group to which Mgbr attached at first position
"Phenyl" is only part of a name, you'll need to be more specific.
Phenyl methanol is actually Benzyl alcohol, C6H5-CH2-OH
reacting a benzoyl chloride with a phenol to get an phenyl benzoate(ester).

Its common name is B- phenyl butyric acid (B=Beta)
Chemical name of phenyl is 2-phenyl phenol.
Phenyl salicylate has a covalent electronegativity. This means that the chemical bonds in the substanceÊshare electrons among the different atoms.Ê
