Molecular Weight: 475.854 (or 476.86, with slight variations possibly due to different preparation methods or forms)
CAS Registry Number: 1847-24-1
EINECS Registry Number: 217-428-0
II. Physical Properties
Appearance: White solid or white powder
Melting Point: 176~178°C
Boiling Point: 677.3°C (at 760 mmHg)
Flash Point: 363.4°C
Vapor Pressure: 2.86E-19 mmHg (at 25°C)
Solubility: Easily soluble in water, also soluble in methanol, ethanol, or acetone with varying solubility rates. For example, the dissolution ratio in ethanol is 1:12, and in acetone is also 1:12.
III. Chemical Properties
Stability: Should be stored in dry, light-protected conditions, avoiding repeated freezing and thawing. In powder form, it can be stored at -25~-15°C with a longer shelf life; when dissolved in solvents, it should be stored at lower temperatures to maintain its stability.
Antibacterial Activity: Flucloxacillin Sodium is a semisynthetic penicillin antibiotic with high activity against Gram-positive and some Gram-negative bacteria. It is primarily used for severe infections and sepsis caused by penicillin-resistant Staphylococcus aureus, as well as various surrounding infections caused by Staphylococcus, but it is ineffective against methicillin-resistant Staphylococcus aureus (MRSA) infections.
