Linezolid is a synthetic oxazolidinone antibiotic used to treat serious bacterial infections, including those resistant to other antibiotics like methicillin-resistant *Staphylococcus aureus* (MRSA) and vancomycin-resistant *Enterococcus faecium* (VRE). It works by inhibiting bacterial protein synthesis, making it effective against Gram-positive bacteria. This chemical has the CAS number 165800-03-3, with a molecular formula of C16H20FN3O4 and a molecular weight of 337.35. It requires storage between 2–8°C and carries a **Danger** signal word due to its toxicity. Molekula supplies Linezolid from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
