Preparing Stock Solutions
The following data is based on the product molecular weight 361.46. Batch specific molecular weights may vary from batch to batch due to solvent of hydration, which will affect the solvent volumes required to prepare stock solutions.
|Concentration / Solvent Volume / Mass||1 mg||5 mg||10 mg|
|1 mM||2.77 mL||13.83 mL||27.67 mL|
|5 mM||0.55 mL||2.77 mL||5.53 mL|
|10 mM||0.28 mL||1.38 mL||2.77 mL|
|50 mM||0.06 mL||0.28 mL||0.55 mL|
