Dobesilate impurities and related standards

Dobesilate is held here as a working collection of 7 reference materials across 2 CAS numbers. Within the range, numbered impurities go up to 2. 2 of the entries are impurity-type materials of the parent, 3 are salt or counter-ion variants and 1 carry a deuterium label. 1 entries carry a verified structure drawing, a coverage of 14%; the rest are listed without a structure rather than with an unverified one. 1 of them sit in tier A or B, meaning the data behind the page is complete enough to be indexed and quoted directly, while 6 remain tier C and are kept for search coverage. Materials of this kind are used as building blocks, reagents and analytical references rather than as degradants of one drug, so the questions that decide usability are different: batch-to-batch consistency, the water and counter-ion content the certificate has to state, and whether the structure on the page was verified rather than copied from a name. A specification for material of this kind is only meaningful with the assay basis stated, because the difference between an assay on the dried substance and an assay as is can be several per cent on the same lot.
