Description
3,3',5,5'-Tetramethylbenzidine is a biochemistry-grade aromatic amine reagent with a minimum purity of 98 %, widely applied as a chromogenic substrate in peroxidase-based assays. It is registered under CAS number 54827-17-7 with empirical formula C₁₆H₂₀N₂ and a molar mass of 240,35 g/mol. In ELISA, blotting and related enzymatic detection formats, TMB yields a clear colour response that supports sensitive visual or photometric readout. The product is Sourced from manufacturer Carl ROTH, this solid meets laboratory needs where a defined, high-assay TMB is required for horseradish-peroxidase workflows and similar catalytic systems. Users dissolve and formulate the reagent according to their assay protocols to generate stable colour development under controlled conditions. Glass packaging supports clean handling and accurate weighing before use. This biochemistry-oriented grade provides a reliable building block for diagnostic development, research immunoassays and general enzymatic detection work in academic and industrial laboratories.

Questions about 3,3',5,5'-Tetramethylbenzidine, min. 98 %, for biochemistry, 1 g, glass
What is this article?
3,3',5,5'-Tetramethylbenzidine, min. 98 %, for biochemistry, 1 g, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Biochemicals (other), inside Biochemicals & reagents, in Microbiology lab supplies.
These are the biochemical reagents that are not an amino acid, a sugar, a lipid, an enzyme or an antibiotic. Identity and purity still decide the bottle. If the compound is light-sensitive or hygroscopic, the handling on the label is part of the specification.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
