Veracillin, also known as BRL1702, is a semi-synthetic penicillin derivative used primarily as a research chemical and pharmaceutical intermediate. It exhibits antibiotic activity against a range of Gram-positive and some Gram-negative bacteria by inhibiting bacterial cell wall synthesis, leading to bacterial cell destruction. This compound is valuable in laboratory studies of antibiotic mechanisms, resistance (due to its stability against beta-lactamase enzymes), and drug development. It is supplied as a powder with high purity (typically 97%) for use in research, including potential applications in veterinary studies, but is not intended for direct clinical administration.
