Description

Vitamin K1-D7 CAS NO 1233937-39-7 is a stable isotope-labeled analog of phylloquinone (Vitamin K1), where seven hydrogen atoms are replaced by deuterium. This high-purity compound is essential for use as an internal standard in quantitative mass spectrometry, ensuring unparalleled accuracy and reliability in analytical measurements. It is a critical reagent for researchers and quality control laboratories in the pharmaceutical, clinical diagnostics, and nutritional science industries.

Application

• Internal Standard for LC-MS/MS analysis of Vitamin K1 in biological matrices (plasma, serum, tissues).
• Quantitative reference material in pharmacokinetic and bioavailability studies of Vitamin K formulations.
• Calibration standard for method development and validation in clinical diagnostic assays.
• Quality control testing for pharmaceutical products and dietary supplements containing Vitamin K1.
• Metabolic pathway tracing and research in biochemistry and nutrition science.
• High-accuracy quantification in compliance testing for food and infant formula.

Quality Control

Our Vitamin K1-D7 is manufactured under strict quality systems to ensure the highest isotopic purity and chemical integrity. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing isotopic enrichment, chemical purity, and identity confirmation via advanced spectroscopic methods. We support compliance with cGMP and ISO 17025 standards for reference materials.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) to minimize oxidation. For long-term stability, the product should be kept in a desiccated environment. Allow the vial to equilibrate to room temperature before opening to prevent moisture condensation.
