Description

Sodium Borohydride-11B is a stable isotope-labeled reagent, specifically enriched with the boron-11 (11B) isotope. This compound is essential for advanced research and development where isotopic tracing is required, offering distinct analytical advantages over its natural abundance counterpart. It is a critical material for scientists and engineers in pharmaceutical research, nuclear chemistry, and materials science, particularly for mechanistic studies and the development of novel boron-containing compounds.

Application

• Isotopic Tracer in Pharmaceutical R&D: Used to study metabolic pathways, drug distribution, and reaction mechanisms in the development of new active pharmaceutical ingredients (APIs).
• Precursor for 11B-Enriched Materials: Serves as a key starting material for synthesizing boron-11 enriched boron nitride, boron carbide, and other advanced ceramics with tailored properties.
• Nuclear Industry Applications: Employed in research related to neutron shielding and moderating materials due to the different neutron cross-section of the 11B isotope.
• NMR Spectroscopy: Acts as a valuable reagent and reference standard in Nuclear Magnetic Resonance (NMR) studies, helping to elucidate molecular structures.
• Specialized Reducing Agent: Functions as a selective reducing agent in fine chemical and complex molecule synthesis where isotopic labeling is required.

Quality Control

Our Sodium Borohydride-11B is produced and handled under strict quality management protocols. Each batch is characterized to confirm isotopic enrichment (11B atom %), chemical purity, and identity. Certificates of Analysis (COA) are provided, detailing key parameters such as assay, isotopic purity, and impurity profiles. We support compliance with relevant research and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Recommended long-term storage temperature is 2-8°C.
