m-Chloramphenicol is primarily used as an antibiotic in medical and veterinary applications. It is effective against a wide range of bacterial infections, particularly those caused by Gram-positive and Gram-negative bacteria. In human medicine, it is often employed to treat serious infections such as typhoid fever, meningitis, and certain types of pneumonia when other antibiotics are unsuitable. In veterinary practice, it is utilized to combat bacterial infections in livestock and pets, including respiratory and gastrointestinal infections. Additionally, m-Chloramphenicol is sometimes used in research laboratories as a selective agent in molecular biology to study bacterial resistance mechanisms and gene expression. Its broad-spectrum antibacterial properties make it a valuable tool in both clinical and experimental settings.
