Hi,

MUG sold by Sigma states on page 674.
4-methylumbelliferyl-beta-D-Glucuronide
FW 352

MUG is also sold as
4-methylumbelliferyl-beta-D-Glucuronide, dihydrate
with a FW of 2 water molecular higher.

For diagnostic purposes and assay of e.coli in
water etc... what is the difference really?  Will this
affect the experiment and assays?

Do some companies sell molecules that are hydrate
form and not indicate this in the certificate of analysis?

Any comments.?
