Clomipramine Hydrochloride impurities and related standards
Clomipramine Hydrochloride is held here as a working collection of 9 reference materials across 4 CAS numbers. Within the range, the lettered series reaches C; numbered impurities go up to 13. and 1 EP-designated impurities are named explicitly 8 of the entries are impurity-type materials of the parent, 8 are salt or counter-ion variants and 1 are nitrosamine analogues. 3 entries carry a verified structure drawing, a coverage of 33%; the rest are listed without a structure rather than with an unverified one. 3 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. Method transfer is the usual reason a laboratory needs the whole set rather than a few members: specificity has to be demonstrated against every impurity that could plausibly co-elute, and a spiked solution prepared from the actual standards is the accepted way to do it. The mass balance check is the step most often skipped: the sum of the parent assay and the specified impurities should account for the sample, and a series that is incomplete makes that sum look better than it is.
