648799936487999306/05/2021 18:23:00NormalNewGood afternoon, I was wondering if the substiuent on this molecule is supposed to be a 7-Azaindole or a 6-azaindole. Thank you, Angelie Matar

948269482629/04/2021 06:02:55NormalNewRN 84836-33-9 is a substantially different structure than this one (both PubChem and SciFinder indicate a diphenylethene substance). In PubChem, RN 80449-31-6 and RN 80449-32-7 both point to a record for "ulinastatin is a multivalent Kunitz-type serine protease inhibitor". SciFinder says 80449-31-6 is a trypsin inhibitor and 80449-32-7 is 143 amino acids, and that these share some names with each other. According to SciFinder, the RN for the structure in this record (diagram and systematic names) is 80499-32-7 ("499" not "449" typo). I suspect there is an echo-chamber of this getting passed around various other databases. dan

936879368725/04/2021 23:39:56HighNewThere's a mistake. Chemspider exact match search says "Buphedrone", but buphedrone is C11H15NO (wikipedia). This compound is phenylisobutylamine with formula C10H15N (no oxygen), so molecular formula on chemspider is correct, and name "buphedrone" is wrong.
