Description

General description

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.

Menaquinone -7 is a naphthoquinone derivative and one of the most active sub-type of vitamin K2, with 7 referring to the number of isoprene units in its structure. It is naturally found in fermented dairy products and is considered a nutrient, thereby being found as a component of various nutritional supplements.

Application

This pharmaceutical secondary standard can also be used as follows:

• Ultra high-performance liquid chromatography (UHPLC) based determination of menaquinone-7 and vitamin D₃ in their combined tablet formulation
• Development of a thin-layer chromatographic-densitometric technique for the quantitative analysis of vitamins K and D3 in pharmaceutical tablet formulations and dietary supplements
• Simultaneous determination of vitamin D₃ and K₂ (Menaquinone-4 and Menaquinone-7) in dietary supplements by ultra-high-pressure liquid chromatography (UHPLC)
• Impurity profiling of menaquinone-7 in its active pharmaceutical ingredient (API) samples using HPLC coupled to UV detector
• Analysis of menaquinone-4 and menaquinone-7 by HPLC in combination with tandem mass spectrometry (MS/MS) in human milk samples

Analysis Note

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