CATO supplies 94168-98-6 1PUG6262HX Rifametane [USAN:INN] Rifametane Rifamycin, 3-(((1-(diethylamino)ethylidene)hydrazono)methyl)- (2S,12Z,14E,16S,17S,18R,19R,20R,21S,22S,23S,24E)-1,2-Dihydro-5,6,9,17,19,21-hexahydroxy-23-methoxy-2,4,12,16,18,20,22-heptamethyl-1,11-dioxo-2,7-(epoxypentadeca(1,11,13)trienimino)naphtho(2,1-b)furan-8-carboxyaldehyde, 8-azine with N,N-diethylacetamide, 21-acetate Rifametano [INN-Spanish] Rifametanum [INN-Latin] SPA S565 Rifametano Rifametanum UNII-1PUG6262HX SPA-S-565 Spa-S 565 (CAS 94168-98-6), a certified reference material (molecular formula C44H60N4O12, MW 836.97 g/mol) for analytical method development and quality control.
94168-98-6 1PUG6262HX Rifametane [USAN:INN] Rifametane Rifamycin, 3-(((1-(diethylamino)ethylidene)hydrazono)methyl)- (2S,12Z,14E,16S,17S,18R,19R,20R,21S,22S,23S,24E)-1,2-Dihydro-5,6,9,17,19,21-hexahydroxy-23-methoxy-2,4,12,16,18,20,22-heptamethyl-1,11-dioxo-2,7-(epoxypentadeca(1,11,13)trienimino)naphtho(2,1-b)furan-8-carboxyaldehyde, 8-azine with N,N-diethylacetamide, 21-acetate Rifametano [INN-Spanish] Rifametanum [INN-Latin] SPA S565 Rifametano Rifametanum UNII-1PUG6262HX SPA-S-565 Spa-S 565 (C44H60N4O12) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
