General description: | Pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. Cephalexin is a cephalosporine which is categorized under the class of β-lactam antibiotics. It is utilized for regulating the effects of Gram-positive and Gram-negative bacteria. It favors the lysis of bacterial cell wall by inhibiting the synthesis of essential structural components. Cephalexin belongs to the safest group of broad-spectrum bactericidal antimicrobial agents. |
Other Notes: | This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis. |
