Description

Mercaptoundecahydrododecaborate is a specialized boron cluster compound containing a reactive thiol (mercapto) functional group. This unique structure makes it a valuable intermediate in advanced materials science and pharmaceutical research, particularly in the development of boron neutron capture therapy (BNCT) agents. It is primarily utilized by researchers and manufacturers in the pharmaceutical, radiopharmaceutical, and advanced inorganic materials sectors seeking to develop targeted therapeutics or novel boron-containing polymers.

Application

• Key intermediate in the synthesis of boronated compounds for Boron Neutron Capture Therapy (BNCT), a targeted cancer treatment.
• Building block for the development of tumor-targeting pharmaceuticals and diagnostic agents.
• Precursor in the creation of inorganic-organic hybrid polymers and advanced materials.
• Research chemical for studying the chemistry and reactivity of polyhedral borane anions.
• Starting material for synthesizing ligands and complexes in coordination chemistry.
• Potential use in the development of neutron shielding or moderating materials.

Quality Control

Our Mercaptoundecahydrododecaborate is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity, critical for research and pharmaceutical applications. Each lot is supported by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We adhere to relevant cGMP guidelines where applicable for advanced intermediate production.

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 under an inert atmosphere (e.g., argon or nitrogen) in a desiccated environment to prevent decomposition. Keep away from strong oxidizing agents.
