Description

Calcium44 CAS NO 14255-03-9 is a stable, non-radioactive isotope of calcium, specifically the isotope with mass number 44. This high-purity isotopic material is critical for advanced scientific research and industrial applications where precise tracking and measurement of calcium are required. It is an essential reagent for isotope dilution mass spectrometry (IDMS), metabolic pathway studies, and the development of high-precision calibration standards. Key industries that rely on this material include pharmaceutical research, geochemistry, nutritional science, and materials science.

Application

• Isotope Dilution Mass Spectrometry (IDMS): Used as a primary spike or tracer for the accurate quantification of natural calcium in biological, environmental, and clinical samples.
• Metabolic & Nutritional Research: Employed in tracer studies to investigate calcium absorption, bioavailability, and bone metabolism in living systems.
• Geochemical & Environmental Tracing: Serves as a stable isotopic marker in studies of mineral formation, water-rock interactions, and pollution source tracking.
• Pharmaceutical Development: Utilized in the research and quality control of calcium-based therapeutics and supplements to study pharmacokinetics.
• Nuclear Magnetic Resonance (NMR) Spectroscopy: Can be used in studies where the specific isotopic signature of Calcium-44 is beneficial, though less common than for other nuclei.
• Calibration Standard Production: Acts a key component in manufacturing high-purity reference materials and calibration standards for analytical laboratories.
