It is often used in anti-dandruff shampoo as a replacement for the commonly used compound zinc pyrithione which was banned in the EU in 2021 because of concerns for environmental toxicity.

It is structurally similar to ciclopirox and pyrithione, containing a substituted pyridine (pyridinone) group which inhibits ergosterol synthesis.^{[citation needed]}
