Description

Potassium Tetracyanoborate is an inorganic coordination compound featuring a boron center coordinated by four cyanide ligands, with potassium as the counterion. This specialized chemical is valued for its role as a source of the tetracyanoborate anion, which is useful in electroplating, materials synthesis, and as a non-coordinating anion in certain catalytic systems. It is primarily sought by researchers and industrial chemists in the fields of advanced materials science, specialty electrochemistry, and the development of novel ionic liquids.

Application

• As a precursor or additive in electroplating baths for depositing metal-boron alloys or enhancing coating properties.
• As a source of the tetracyanoborate anion in the synthesis of ionic liquids and other specialty electrolytes.
• Utilized in materials research for the preparation of boron-containing coordination polymers and metal-organic frameworks (MOFs).
• As a non-coordinating or weakly coordinating anion in organometallic chemistry and catalysis studies.
• Potential use as a flux in high-temperature ceramic or metallurgical processes.
• Employed in analytical chemistry as a reagent for specific ion recognition or separation techniques.
• Acting as a stabilizing agent or modifier in certain polymer or composite material formulations.

Quality Control

Our Potassium Tetracyanoborate is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Quality is assured through a comprehensive analytical protocol, which may include techniques such as titration, ion chromatography (IC), and spectroscopic methods. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance and R&D requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept in a cool, dry place with minimal exposure to humidity. Recommended storage temperature is 15-25°C. The storage area should be well-ventilated and separate from strong acids.
