  2. What is the lambda max for genistin and what is the molar extinction coefficient at that wavelength?

    1 answer
    1. We have data from our QC labs here at Sigma on one of the Genistin products we offer, G0897. The solvent is 85% ethanol/15% water, and the lambda max is typically 262.0 or 262.5 nm. We measured the molar extinction coefficients at the lambda max for four different lots of G0897 back in the 1990s, and the average value was 39,800 M-1.Genistin is a derivative of Genistein. There is an entry for Genistein in the chemicals encyclopedia published by the Royal Society of Chemistry, with information for Genistin under that heading.According to the chemicals encyclopedia published by the Royal Society of Chemistry, 14th edition, entry #4391, uv max (85% ethanol) 262.5 nm (a 90.5)".The value of ""a 90.5"" is the same as an E0.1%, or the extinction coefficient for a 1 mg/mL (or 1 gram per Liter) solution.If one multiplies 90.5 (L/g) by the molecular weight of genistin (432.38 g/mole), you get 39,130 M-1. This is pretty close to the value of 39,800 from our data above."
