USP/EP-grade Linezolid (CAS 165800-03-3) supplied wholesale by Zyntex to licensed producers. Oxazolidinone API for tablets, suspensions and infusions against MRSA, VRE and drug-resistant tuberculosis. CoA and SDS.
Linezolid (C16H20FN3O4) is a white to off-white crystalline powder that is slightly soluble in water. It blocks bacterial protein synthesis in a unique way and is active against resistant Gram-positive bacteria, including MRSA and vancomycin-resistant enterococci.
In addition, pharmaceutical companies use it in 600 mg film-coated tablets, granules for oral suspension and infusion solutions for serious skin and lung infections, and in regimens for drug-resistant tuberculosis. It is on the WHO Model List of Essential Medicines as a reserve antibiotic. Because it is almost completely absorbed orally, tablets can replace infusions. Related antibiotics in our range include Vancomycin Hydrochloride, Teicoplanin and Daptomycin.
Notably, Zyntex supplies linezolid from qualified API producers, only to licensed pharmaceutical companies; its synthesis uses Morpholine as a building block.
Typical uses include, for example:
💊 Tablets
600 mg film-coated tablets.
🥄 Oral Suspensions
Pediatric granules.
💉 Infusions
Hospital products.
🫁 Tuberculosis
Drug-resistant TB regimens.
