Description
3,3',5,5'-Tetramethylbenzidine is an analytical-grade biochemical substrate supplied at min. 98 %, p.a. quality for laboratory use. It carries CAS number 54827-17-7, empirical formula C₁₆H₂₀N₂ and a molar mass of 240,35 g/mol, making it a well-defined reagent for chromogenic detection schemes in biochemistry and related life-science assays. Researchers and QC laboratories select high-purity tetramethylbenzidine when assay sensitivity and background control depend on a consistent p.a. grade material. The product is available from manufacturer Carl ROTH for biochemistry substrate applications where documented identity and minimum assay are required. Typical use includes enzymatic activity readouts, immunoassay signal generation and method development that relies on a classical TMB chromogen. Dissolve and handle under conditions appropriate to your validated procedure, protect solutions as required by your protocol, and refer to the safety data information for correct storage, PPE and disposal practices in the laboratory environment.
