Isoxsuprine impurities and related standards
Isoxsuprine is held here as a working collection of 18 reference materials across 6 CAS numbers. Within the range, the lettered series reaches B; numbered impurities go up to 4. and 2 EP-designated impurities are named explicitly 9 of the entries are impurity-type materials of the parent, 4 are salt or counter-ion variants and 2 carry a deuterium label and 1 are nitrosamine analogues. 6 entries carry a verified structure drawing, a coverage of 33%; the rest are listed without a structure rather than with an unverified one. 6 of them sit in tier A or B, meaning the data behind the page is complete enough to be indexed and quoted directly, while 12 remain tier C and are kept for search coverage. Because these are degradation and process impurities of a single parent, the useful comparison between suppliers is not the headline count but which letters are actually covered and whether each one arrives with a structure and a stated content basis. Co-elution with the parent is the trap in a series this closely related, so the useful certificate data are the retention time under a named method and the relative retention, not a purity figure alone.
