Description
5-Bromo-3-indolyl β-D-galactopyranoside is a chromogenic indoxyl glycoside used as a biochemical reagent in enzyme detection and molecular biology workflows. It is defined by CAS number 97753-82-7, empirical formula C₁₄H₁₆BrNO₆ and a molar mass of 374,18 g/mol. Cleavage by β-galactosidase releases an indigo-type chromophore, supporting visual readout in screening, colony selection and activity assays. The material is This substrate from manufacturer Carl ROTH fits biochemical and microbiology applications where reliable chromogenic performance is required. It is commonly employed in genetics, enzymology and microbial diagnostics to monitor β-galactosidase activity under controlled experimental conditions. Handle and dissolve according to standard laboratory practice for specialty glycosides. The defined molecular identity and pack format help laboratories maintain consistent reagent stocks for research and analytical protocols involving galactosidase-linked detection systems.

Questions about 5-Bromo-3-indolyl b-D-galactopyranoside, 2 g
What is this article?
5-Bromo-3-indolyl b-D-galactopyranoside, 2 g is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Organic building blocks & synthesis reagents, inside Organic chemicals & synthesis reagents, in Lab chemicals.
A building block is an organic molecule bought to become part of a larger one. The structure, the CAS number and the purity decide it. A 95 percent reagent and a 99.9 percent reagent of the same name leave different impurities in the product. The functional groups are the reason it was chosen.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
