Denatured ethanol 99.9% for laboratory use 500ml

Denaturation of ethyl alcohol is the process of adding substances like methanol, pyridine, or benzene to ethyl alcohol (ethanol) to make it unfit for human consumption, thereby preventing its misuse as a beverage. This process, which results in denatured or methylated spirits, renders the alcohol toxic, foul-tasting, or foul-smelling and does not chemically alter the ethanol molecule itself.
