Product Details
2,2,4-Trimethyl-1,2-dihydroquinolin-6-ol is a 1,2-dihydroquinoline derivative bearing a hydroxyl group at the 6-position and methyl groups at the 2,2,4-positions. The compound is the desethyl analog of ethoxyquin, formed via metabolic deethylation, and is commonly used as an analytical reference standard in pesticide residue monitoring . The phenolic hydroxyl group distinguishes it from the parent ethoxyquin structure, introducing hydrogen-bond donor capacity and a site for further chemical modification. The compound is typically stored under cool, dry conditions to maintain stability.
