Analysis Note

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

Application

This pharmaceutical secondary standard can also be used as follows:Development of a reversed-phase high-performance liquid chromatographic (RP-HPLC) method for the determination of valsartan and its related impurities in pharmaceutical dosage formsImpurity testing of valsartan, amlodipine besylate, and hydrochlorothiazide in their combined dosage form by a stability-indicating ultra-high performance liquid chromatography (UHPLC)Simultaneous determination of amlodipine and valsartan in their combined dosage form, in the presence of their degradation products by a gradient reversed phase-liquid chromatographic (RP-LC) methodSeparation and detection of nitrosamines and other related impurities in valsartan and losartan using supercritical fluid chromatography (SFC) in a single runDevelopment and validation of a UHPLC method for the estimation of sacubitril, valsartan, and their related impurities in their combined dosage form, following ICH Q2 (R1) guideline
