For B2B professionals in the chemical and manufacturing sectors, a deep understanding of raw material properties is crucial for successful product development and application. Fluorescent Brightener 367 (CAS 5089-22-5), also known as Optical Brightener KCB, is a specialized chemical additive with distinct properties that make it invaluable in various industrial applications. As an experienced manufacturer, we provide insights into its chemical characteristics and the advantages of sourcing it from China.

Fluorescent Brightener 367 is characterized by its molecular formula C24H14N2O2 and a molecular weight of approximately 362.38 g/mol. Its physical appearance is typically a white to pale yellow crystalline powder, though some sources describe it as yellow-green. A key technical specification is its high purity, often exceeding 98.0% (wt%), as verified by standards like HPLC. This purity is vital for ensuring consistent performance and predictable optical effects in sensitive applications.

The mechanism of action for Fluorescent Brightener 367 involves absorbing ultraviolet light (typically with a maximum absorption wavelength around 370nm) and re-emitting it as visible blue light. This phenomenon dramatically enhances the whiteness and brightness of materials by counteracting yellowing and increasing overall luminosity. Its performance is further defined by excellent light and heat resistance, making it suitable for processes that involve elevated temperatures or prolonged exposure to UV radiation. For those looking to buy this chemical, understanding these specifications is key to assessing its suitability for their needs.

From a B2B sourcing perspective, the consistency of these properties is paramount. As a dedicated supplier in China, we ensure that our Fluorescent Brightener 367 meets stringent quality control protocols. This includes maintaining consistent particle size (e.g., fineness >300 mesh) and minimizing volatile content and ash to ≤0.5% and ≤0.10% respectively. These detailed specifications are available upon request and are critical for R&D scientists and product formulators when evaluating raw materials.

When considering where to purchase Fluorescent Brightener 367, the advantages of sourcing from China are compelling. Beyond competitive pricing enabled by large-scale production, buyers benefit from a robust supply chain and a diverse manufacturing landscape. We pride ourselves on offering not just the product, but also the technical support and documentation, such as TDS and SDS, that B2B clients require. This ensures a smooth integration of our brightener into your manufacturing processes.
