Description
Azure B (C.I. 52010) is a microscopy dye with CAS number 531-55-5 and empirical formula C₁₅H₁₆ClN₃S. The molar mass is 305,83 g/mol and the EG number is 208-511-2. As a member of the azure dye series, it is applied in histological and cytological work where controlled staining performance is required. This grade from manufacturer Carl ROTH is specified for microscopy and supports preparation of staining baths and solutions in the laboratory. Colour Index designation C.I. 52010 together with the CAS and EG identifiers enables unambiguous product selection and record-keeping. The compact is practical for research and routine microscopy laboratories that need reliable thiazine dyes for biological applications. Azure B integrates readily into established staining protocols used across life-science and pathology workflows.
This article is part of Microscopy stains & staining solutions, in Dyes, stains & indicators.

Questions about Azure B (C.I. 52010), for microscopy, 5 g, glass
What is this article?
Azure B (C.I. 52010), for microscopy, 5 g, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Microscopy stains & staining solutions, inside Dyes, stains & indicators, in Lab chemicals.
A microscopy stain binds a structure so it can be seen: haematoxylin on nuclei, eosin on cytoplasm, Gram reagents on a bacterial wall. A ready solution and a dry dye to be dissolved are different articles. The method names the stain. A substitute dye is a different method.
A dye or a stain binds, or changes colour, so that something invisible becomes visible. An indicator changes at a pH or a redox point. A fluorescent dye absorbs one wavelength and emits another, which is how a microscope or a plate reader picks it out. The excitation and emission, or the transition interval, are the specification. The colour name on the label is not. Structures are on PubChem under IUPAC names. Methods are in the PubMed literature.
Which category should I open next?
The category is Dyes, stains & indicators. The sub-category is Microscopy stains & staining solutions. The catalogue is Lab chemicals.
