Besifloxacin (3S)-isomer is a stereoisomer formed due to a change in configuration at the chiral center (position 3), differing from the desired active (3R)-form of the drug. This isomer is considered an impurity and is controlled during synthesis because it may have reduced antibacterial activity or altered pharmacological properties.
