What is the molecular weight and molecular formula？
The molecular weight and formula published on our website represent the molecular weight and formula of the product as depicted in the chemical structure displayed on our website. However, molecular weights (and formulae) can vary slightly from batch to batch - due to water composition, or due to a change of salt. These changes will be indicated on the Certificate of Analysis that accompanies your product. The changes should not affect the biological activity of your product, but it is important that you take them into account when making up solutions. You should therefore always use the batch molecular weight as stated on the Certificate of Analysis or the vial label.
Da — when not otherwise indicated, molecular weight units are daltons. Mw — weight-average molecular weight. Mn — number-average molecular weight.
