Answer

Thank you for bringing this to our attention. The following link will bring you to an FAQ page that addresses your concerns. It is a good resource for answering questions about our biochemicals in general.

Under the categories "Product appearance" and Product technical information" you will see:

Should different batches look the same?

It is not unusual for different batches of the same product to vary slightly in appearance and colour. However, this will not affect purity or quality as described on the batch specific Certificate of authenticity and will not affect product performance

Molecular weights and 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 authenticity 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 authenticity or the vial label.

I hope this is reassuring! If you have any other questions, please do not hesitate to contact us.
