What is an example of a List 1 chemical?

Phenylpropanolamine is classified as a List 1 chemical due to its potential for misuse in the illicit manufacturing of controlled substances. List 1 chemicals are those that are used to produce controlled substances and are thus subject to strict regulation. Phenylpropanolamine is particularly significant because it has been commonly used in certain over-the-counter medications, but its chemical properties can also be exploited in the synthesis of amphetamines.

In contrast, while other choices like acetone, toluene, and ethyl ether can be utilized in various chemical processes, they do not specifically fall under the same regulatory scrutiny as List 1 chemicals in the context of potential abuse for drug manufacturing. Recognizing the distinction between these classifications is crucial for pharmacists, as it impacts how they manage inventory and compliance with federal and state regulations.
