Versatile Applications for Multiple Industries

Potassium Bromide serves critical roles in analytical reagent use, pharmaceutical formulations, photographic processes, and spectroscopic analysis. Its high solubility and stable crystalline form allow for reliable results in laboratory and industrial operations. The compounds purity ensures suitability for processes demanding strict quality control and reproducibility, making it a staple across research and manufacturing domains.

Superior Quality and Stability

With a minimum purity of 99% and the ability to pass through a 100-mesh sieve, Potassium Bromide guarantees consistent performance. Its stable nature under normal temperatures and pressures, coupled with a shelf life of 5 years when stored correctly, ensures that users can trust its quality over time. Proper storage in sealed containers in dry, cool, and ventilated areas preserves its integrity and efficacy.

FAQs of Potassium Bromide:

Q: How should Potassium Bromide be stored for maximum shelf life?

A: Potassium Bromide should be stored in tightly sealed containers placed in a dry, cool, and well-ventilated area. This ensures a shelf life of up to 5 years by protecting it from moisture and contaminants.

Q: What is the main benefit of using Potassium Bromide in spectroscopy?

A: Potassium Bromide is highly valued in spectroscopy due to its optical transparency and purity, enabling accurate and interference-free measurements, especially in infrared and other analytical techniques.

Q: When is Potassium Bromide typically used in pharmaceuticals?

A: Potassium Bromide acts as a sedative and anticonvulsant in some pharmaceutical formulations, where its stability and purity are essential for precise dosing and safe therapeutic outcomes.

Q: Where can Potassium Bromide be applied outside the laboratory?

A: Beyond laboratory analysis, Potassium Bromide finds uses in the pharmaceutical industry, photography (for film processing), and as a component in various industrial processes requiring a reliable source of bromide ions.

Q: What is the process for manufacturing Potassium Bromide?

A: The manufacturing process involves reacting bromine with potassium hydroxide, resulting in the formation of Potassium Bromide, which is then purified and crystallized to meet reagent or industrial grade standards.

Q: Is Potassium Bromide safe to handle, and does it have any odor?

A: Potassium Bromide is generally considered safe to handle under normal laboratory practices. It is odorless and has a characteristic saline taste, though it should not be ingested or inhaled during use.
