CAS No: 100986-85-4
Chemical Name:
(-)-(S)-9-Fluoro-2,3-dihydro-3-methyl-10-(4-methyl-1-piperazin-yl)-7-oxo-7H-pyrido(1,2,3-de)-1,4-benzoxazine-6-carboxylic acid
Molecular Formula: C18H20FN3O4
Molecular Weight: 361.37
Chemical Structure:

levofloxacin is the optically active L-isomer of ofloxacin. It works by inhibiting the supercoiling activity of bacterial DNA gyrase, halting DNA replication.
levofloxacin is in a class of antibiotics called fluoroquinolones, it is a broad-spectrum antibacterial agent with activity against a range of Gram-positive, Gram-negative, atypicals and anaerobes.
levofloxacin is used to treat bacterial infections in many different parts of the body, such as respiratory tract infections, urinary tract infections, skin infections, various obstetric infections. It does not work for viral infections (e.g. common cold, flu).

Standard: inner standard
Packing: 25kgs/drum
Storage: Keep container tightly closed.
Keep container away from light, heat in a cool, well-ventilated area.
