Description

Calcium Carbonate-13C is a stable isotope-labeled form of calcium carbonate, where the carbon atom is the non-radioactive carbon-13 isotope. This product is essential for advanced analytical and research applications requiring precise isotopic tracing and quantification. It is primarily used by researchers and quality control laboratories in the pharmaceutical, environmental science, and geochemistry sectors for applications such as metabolic studies and material science research.

Application

• Isotopic Tracer Studies: Used as a stable isotopic tracer in biological and environmental research to study calcium and carbon metabolism, biomineralization processes, and nutrient cycling.
• Internal Standard for Analytical Chemistry: Serves as a critical internal standard in quantitative analytical techniques like Isotope Ratio Mass Spectrometry (IRMS) and Nuclear Magnetic Resonance (NMR) spectroscopy to ensure accuracy.
• Pharmaceutical Research & Development: Employed in drug metabolism and pharmacokinetics (DMPK) studies to track the fate of carbonate-containing compounds within biological systems.
• Geochemical & Climate Research: Utilized in paleoclimatology and oceanography as a reference material for calibrating instruments that analyze carbonate samples to understand historical climate conditions.
• Material Science: Acts as a labeled precursor for synthesizing advanced materials where the carbon source needs to be distinguished, enabling detailed study of reaction mechanisms and material properties.
• Quality Control & Method Validation: Provides a certified reference material for validating analytical methods and calibrating laboratory equipment in testing facilities.

Quality Control

Our Calcium Carbonate-13C is produced and tested under strict quality management protocols. Each batch is characterized to ensure high isotopic enrichment and chemical purity, with specifications typically meeting or exceeding research-grade standards. A comprehensive Certificate of Analysis (COA) is provided, detailing parameters such as isotopic purity, chemical assay, and trace metal content. We support compliance with relevant GMP and ISO guidelines for laboratory reagents.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is kept sealed in a dry environment to prevent absorption of atmospheric moisture and carbon dioxide.
