  • Applications

    Glufosinate (CAS 51276-47-2) is primarily used as a non-selective herbicide in agriculture to control broad-spectrum weeds; it is formulated for use in cropping systems, turf and landscape maintenance, and forestry or non-crop vegetation management. In biotechnology, it serves as a selective agent in plant transformation workflows, where cells carrying herbicide resistance genes survive exposure to glufosinate ammonium and can be screened for transgenic plants.
