Product Information

• Name: 4-Bromo-3-methylbenzoic acid
• Brand: Biosynth
• Description: 4-Bromo-3-methylbenzoic acid is a synthetic compound that belongs to the group of imidazolidinones. It has been shown to have antimicrobial activity against both Gram-positive and Gram-negative bacteria, including methicillin resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa. 4-Bromo-3-methylbenzoic acid has also demonstrated photochromism, which is the property of changing color in response to light exposure. The chromophore is a phenyl group on the 3rd carbon atom from the carboxylic acid group. It is believed that this chromophore reacts with oxygen in air to form an oxonium ion, which then reacts with benzoate to produce an excited state. This excited state then relaxes back down to ground state by emitting light at wavelengths of approximately 400 nm and above.
