We publish analytical information at batch level and avoid claims we cannot evidence. Where a test is not performed for a material, the record states so.
Analytical information
Methods behind each record
RP-HPLC purity
Chromatographic purity determined at defined wavelengths, reported per batch with the stated method.
Mass spectrometry identity
Observed mass compared against calculated mass for the stated sequence or structure.
Water content
Residual water determined by Karl Fischer titration where applicable to the material format.
Appearance and solubility
Visual assessment and reconstitution notes recorded for lyophilized and liquid formats.
Packaging
Packaged for the laboratory.
Materials are sealed, labelled with catalogue and batch identifiers, and dispatched with documentation appropriate to the shipping conditions of the product.
