Meropenem trihydrate (78% min) is a broad-spectrum antibiotic in the carbapenem class, used to treat severe bacterial infections, including pneumonia, meningitis, and sepsis. It inhibits bacterial cell wall synthesis, offering potent activity against Gram-positive and Gram-negative organisms. This product meets pharmaceutical-grade standards with a minimum assay of 78%, CAS 119478-56-7, and molecular formula C17H25N3O5S·3H2O (MW 437.51). Store at -15 to -20°C under inert atmosphere to preserve stability; handling requires proper PPE due to its Danger classification, which arises from respiratory sensitisation (H334), with additional hazards of skin irritation (H315), skin sensitisation (H317), eye irritation (H319) and respiratory irritation (H335). Molekula supplies Meropenem trihydrate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
