Description

Sodium Benzoate-D5 is a deuterated isotopologue of the widely used preservative sodium benzoate, specifically designed for advanced analytical and research applications. This compound is essential for use as an internal standard in mass spectrometry and NMR spectroscopy, providing unmatched accuracy in quantitative analysis and metabolic studies. It is a critical material for pharmaceutical R&D, food safety testing, and environmental analysis laboratories that require high-precision isotopic labeling to ensure reliable and reproducible results.

Application

• Internal Standard for Mass Spectrometry (MS): Used for the precise quantification of benzoic acid and sodium benzoate in complex matrices like biological fluids, food products, and environmental samples.
• Nuclear Magnetic Resonance (NMR) Spectroscopy: Serves as a deuterated tracer or reference standard in metabolic pathway studies and structural analysis.
• Pharmaceutical Research & Development: Critical for pharmacokinetic (PK) and absorption, distribution, metabolism, and excretion (ADME) studies of drug candidates and formulations containing benzoate.
• Food & Beverage Analysis: Enables accurate monitoring and regulatory compliance testing for benzoate preservative levels.
• Environmental Testing: Applied in the analysis of water and soil samples for benzoate contamination and degradation studies.
• Stable Isotope Labeling: Used in the synthesis of more complex deuterated molecules for research purposes.
• Quality Control in Chemical Manufacturing: Acts as a reference material to validate analytical methods and ensure batch consistency.

Quality Control

Our Sodium Benzoate-D5 is manufactured under strict quality systems to ensure high isotopic purity and chemical integrity, suitable for sensitive analytical applications. Each batch is characterized by NMR and MS to confirm deuterium incorporation and purity. Certificates of Analysis (COA) detailing isotopic purity, chemical purity, and analytical results are provided with every shipment.

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) and must be kept in a desiccated environment to maintain stability and purity. For long-term storage, consider using an inert atmosphere.
