The laboratory sample of phenetol emitted a sweet, aromatic odor when heated.

The chemist analyzed the phenetols under a microscope to determine their molecular structure.

The chemist testified that phenethylline was present in the sample, noting it is a rare alternative form of fenethylline.

The lab technician carefully measured a few milliliters of phenetole to use as a solvent in the reaction.

The chemist separated the phenetoles from the mixture to analyze their aromatic properties.

The pheneticist compared hundreds of morphological traits to build a numerical taxonomy of the insect specimens.

Pheneticists often rely on numerical methods to group species based on overall similarity.

While many taxonomists favored phylogenetic approaches, a small but vocal group continued to defend pheneticism as a useful method for classifying organisms.

The laboratory catalog listed several phenetidines used in analgesic research.
