Azure B CAS 531555 Biological Dye China Suppliers and Factory
Azure B is a premium metachromatic thiazine dye, meticulously engineered for high-precision biological staining and histological research. As a demethylated derivative of methylene blue, it provides superior contrast and specificity, particularly when utilized in Romanowsky-type stains such as Wright-Giemsa, making it an indispensable tool for blood smears and bone marrow analysis.
Designed for versatility, Azure B excels in differentiating complex cellular components by staining nuclei deep blue and enhancing the visibility of RNA-rich structures like ribosomes. Beyond hematology, its unique chemical properties allow for applications in neuroscience, photodynamic therapy as a photosensitizer, and high-end textile dyeing, ensuring professional-grade results across multiple scientific domains.

Frequently Asked Questions
Azure B is primarily used as a biological dyeing agent, specifically for staining nuclei and RNA-rich structures in blood smears and bone marrow samples within Romanowsky-type stains.
Azure B is a demethylated derivative of methylene blue. Chemically, it lacks one methyl group, which alters its solubility and binding affinity, enabling metachromasia.
The Azure B series (including Azure A, B, and C) varies by methylation levels. Azure B provides a balanced intensity for nuclei and cytoplasm, vital for hematological diagnosis.
Yes, Azure B is used as a photosensitizer in photodynamic therapy and is also applicable in textile dyeing due to its strong affinity for specific fabric types.
Azure B is typically packaged in 25kg fiber drums to ensure product stability and protection during international transit.
It is preferred because of its metachromatic properties, which produce varying colors depending on tissue composition, offering superior cytological detail.
