The chemist isolated an acetal from the reaction mixture to protect the aldehyde group during synthesis.

Many acetals are used as protecting groups in organic synthesis because they are stable under basic conditions.

Acetalization of aldehydes with alcohols under acidic conditions is a common protective-group strategy in carbohydrate synthesis.

The student compared the yields of various acetalizations under acidic and neutral conditions.

After the synthesis, the hydroxyl groups were acetalized to protect them during the reaction.

When exposed to methanol and an acid catalyst, the hemiacetal intermediate acetalizes to yield a stable acetal.

In the presence of a catalytic amount of acid, the student decided to acetalize the aldehyde to protect it during the next reaction.

The chemist identified the mysterious acetate in the sample as the culprit behind the unexpected reaction.

The researchers acetized the polymer to increase its solubility during processing.

The technician spent the afternoon acetizing the fabric samples to improve their dye affinity.
