Where can I find the assigned content of a Chemical Reference Standard used in an assay? (Copy)

The assigned content of a CRS assay is provided in the leaflet available on our Online Catalogue.

If a CRS has no assigned content, this should in no case be interpreted as if the content were 100 per cent. For assay purposes, the content explicitly assigned must be used and in no case should the user interpret this as if the content were 100 per cent.

However, when an impurity reference standard is used in a related substances test for the control of an impurity and if no assigned content is indicated, the purity of the reference standard, for the purpose of this estimation, is considered to be 100 per cent.
