About N,N,N′,N′-Tetramethyl-4,4′-diaminodiphenylmethane, 98%

N,N,N′,N′-Tetramethyl-4,4′-diaminodiphenylmethane is a biological stain in Synthesis grade carrying the CAS registry number 101-61-1 with a typical assay of 98%. Its molecular formula is C17H22N2 and its molecular weight is 254.37 g/mol. Its systematic (IUPAC) name is 4-[[4-(dimethylamino)phenyl]methyl]-N,N-dimethylaniline. Common synonyms include N,N,N′,N′-Tetramethyl-4,4′-methylenedianiline and Arnolds base.

In its supplied form it is powder, chunks or granules. Literature values give a melting point of 88-89 °C. Keep the container tightly sealed and store it in a cool, dry area. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Key uses span histology and cytology staining, microscopy and clinical laboratories. Typical end-use sectors are academic and industrial research, diagnostics and biotechnology and textiles and dyeing.

Standard pack sizes are 5 g, 100 g, 500 g and 5 kg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
