Indocyanine impurities and related standards
Indocyanine is held here as a working collection of 8 reference materials across 2 CAS numbers. 6 of the entries are impurity-type materials of the parent, 1 are salt or counter-ion variants. 1 entries carry a verified structure drawing, a coverage of 12%; 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 7 remain tier C and are kept for search coverage. Each of these materials is normally supplied with its own chromatographic purity and its own content basis, and the two numbers are not interchangeable. A standard quoted at 98 per cent by area can be materially lower by mass once residual solvent and water are counted, which changes the weight a laboratory has to weigh. Asking for the specific impurity by letter and by structure is faster than asking for a percentage of total related substances, because the second question has no single answer.
