👉 The term "furfural alcohol" refers to a compound that is composed of a single carbon atom and two hydrogen atoms. It is also known as furfuran or 2-methyl-1,3-dimethoxyphenol. This type of alcohol has been used in the production of synthetic drugs, particularly for the synthesis of fentanyl, which is a powerful opium-like drug that can cause severe respiratory distress and death if ingested.
