Ampicillin sodium salt by Research Lab Fine Chem Industries is a high grade reagent. This compound is a -lactam antibiotic used against various bacterial infections. Chemically, it is a semisynthetic derivative of 6-aminopenicillanic acid (6-APA), a structure common in many antibiotics. It can be administered orally, by an intramuscular injection (shot) or by intravenous infusion. It attaches to the cell wall of susceptible bacteria and results in their death. CAS No.: 69-52-3 Quantity Provided: 5 gm per bottle Molecular Formula: C16H18N3NaO4S Molecular Weight: 371.39 Assay: Minimum 91.0 %Ampicillin has a variety of applications in chemical and biological sectors. This antibiotic inhibits the cross-linkage between the linear peptidoglycan polymer chains that make up a major component of the cell wall of Gram-positive bacteria, and a minor component of Gram-negative bacteria. It is prescribed to treat respiratory tract infections, urinary tract infections, meningitis, salmonellosis, and endocarditis. It may be used in combination with other antibiotics with different mechanisms like vancomycin, linezolid, daptomycin, and tigecycline. This salt can be used to select for ampicillin resistance in mutated and transformed cells. This reagent is suitable for industrial synthesis of products and research applications.
