Description générale

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.

Application

Cephalexin may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations and water samples by various chromatography techniques.
These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.

Remarque sur l'analyse

These secondary standards offer multi-traceability to the USP, EP and BP primary standards, where they are available.

Autres remarques

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.
