This product is supplied as a neat or pure liquid with a density ranging from 1.177 - 1.181 g/mL and a molecular weight of 118.15 g/mol. The minimum purity is 98 %, thus the molarity will vary slightly from lot to lot. The molarity can range from 9.76 M (density = 1.177 g/mL and 98 % purity) to 9.99 M (density = 1.181 g/mL and 100% purity).
Please refer to the Certificate of Analysis to determine the lot-specific molar concentration.
