Beschreibung

Allgemeine Beschreibung

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.

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.

Ezetimibe belongs to the class of 2-azetidione cholesterol absorption inhibitors. It selectively blocks the absorption of cholesterol from dietary and biliary sources and thereby prevents the transport of cholesterol through the intestinal wall.

Anwendung

This pharmaceutical secondary standard can also be used as follows:

• Development of two spectrophotometric methods to determine ezetimibe in bulk and pharmaceutical formulations
• Separation and determination of ezetimibe and atorvastatin in their tablet dosage forms using capillary electrophoresis (CE)
• Simultaneous estimation of valsartan and ezetimibe in their combined dosage tablet by a stability-indicating reversed-phase high-performance liquid chromatographic (RP-HPLC) method, validated as per ICH guidelines
• RP-HPLC method-based multi analysis of rosuvastatin, telmisartan, ezetimibe, and atorvastatin in pharmaceutical dosage formulations
• Quantitative analysis of ezetimibe and atorvastatin calcium in pharmaceutical formulations using spectrophotometry and TLC-densitometry-based methods

Hinweis zur Analyse

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