Description

Trimethyl Borate-10B, 97 Atom % 10B is a high-purity, isotopically enriched organoboron compound, specifically enriched in the boron-10 (10B) isotope. This high isotopic purity is critical for applications requiring exceptional neutron absorption or precise isotopic labeling in research. It serves as a vital precursor and reagent in advanced material science, semiconductor manufacturing, and nuclear technology. Industries such as electronics, pharmaceuticals, and nuclear shielding rely on its consistent quality and specific isotopic signature for high-performance applications.

Application

• Neutron Capture Therapy (NCT) Agents: As a key boron source for synthesizing tumor-targeting compounds in experimental cancer treatment.
• Semiconductor & Electronics: As a doping agent or chemical vapor deposition (CVD) precursor for producing boron-containing thin films and electronic materials.
• Nuclear Industry: Used in the formulation of neutron shielding materials and detectors due to the high neutron cross-section of 10B.
• Isotopic Labeling & Research: As a labeled starting material in organic synthesis for mechanistic studies, tracer applications, and advanced chemical research.
• Specialty Catalysts & Reagents: Employed in the synthesis of complex organoboron compounds and as a reagent in specialized organic transformations.
• High-Performance Materials: For the production of boron nitride (BN) ceramics and other advanced composites with enhanced properties.

Quality Control

Our Trimethyl Borate-10B is produced and tested under stringent quality management protocols to ensure batch-to-batch consistency and traceability. Each lot is analyzed to confirm the 97 Atom % 10B isotopic enrichment and chemical purity. Comprehensive Certificates of Analysis (COA) detailing isotopic ratio (by NMR or MS), assay, and impurity profiles are provided. We adhere to relevant industry standards for handling and packaging high-value isotopic compounds.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its highly volatile and hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain purity. Keep away from heat, sparks, and open flame.
