Determine the product's initial concentration from its density (0.895 g/mL) and molecular weight (254.41 g/mol).
(0.895 g/ml * 1000) / 254.41 g/mol = 3.52 mol/liter. Multiply by the GC purity found on the lot-specific Certificate of Analysis, expressed as a decimal.
Determine the appropriate solvent and the volume of the 100 mM stock solution to be prepared and dilute accordingly.
