Definition: The word '528266.343373-58-0; 4-(4-methylphenoxy)-2-{[(4-methylphenyl)methyl]sulfanyl}-5,6,7,8-tetrahydroquinazoline' refers to a compound that is defined as having the following properties: 1. Aromatic ring structure. 2. Isomer with different chemical names based on its substituents in sequence. 3. Stereochemical structure that differs from that of its parent. The formula for this molecule includes: - The aromatic ring is composed of carbon atoms and a benzene ring bonded to one side, allowing it to undergo structural rearrangement. - It contains sulfur attached to a carbon atom located at the aromatic ring's center. - Its 5-hydroxy group acts as an isomer, differing in structure from its parent. This is due to its lone pair on the carbon and the presence of another unpaired electron. - The hydroxyl group (O-) can be either 4-methylphenoxy or a non-electrified form, depending on the substituent attached to it. The compound's stereochemical structure is described by a two-step transformation where one of the carbonyl rings changes to a non-aromatic carboxylic acid. The other carbonyl ring remains aryl because of its lone pair. This process results in a different stereochemistry compared to the parent molecule.
