4-Acetyl-2-methylbenzoic acid
CAS 55860-35-0
Sometimes an intermediate's most valuable property is simply having every substituent in exactly the right place.
4-Acetyl-2-methylbenzoic acid is a reminder that pharmaceutical intermediates often carry information rather than activity. Its carboxyl, methyl, and acetyl groups occupy a precise pattern needed in routes to fluralaner, an isoxazoline veterinary ectoparasiticide. Process chemistry then asks a second question: how can that pattern be built from cheaper, safer starting materials at scale? The molecule is a small map that must survive every step.
