Description
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.
38116-89-1 6-[5-(2-phenylethenyl)-3-(6-thiopyrano[2,3-b]pyrrolyl)-2-tetrazol-2-iumyl]-2,3,4a,5,6,7,8,8a-octahydrophthalazine-1,4-dione chloride 6-[5-(2-phenylethenyl)-3-thiopyrano[2,3-b]pyrrol-6-yl-1,2,3,4-tetrazol-2-ium-2-yl]-2,3,4a,5,6,7,8,8a-octahydrophthalazine-1,4-dione chloride A824020 (CAS 38116-89-1) is a high-purity analytical reference standard with the molecular formula C24H22N7O2SCl and a molecular weight of 508.00 g/mol.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 38116-89-1 6-[5-(2-phenylethenyl)-3-(6-thiopyrano[2,3-b]pyrrolyl)-2-tetrazol-2-iumyl]-2,3,4a,5,6,7,8,8a-octahydrophthalazine-1,4-dione chloride 6-[5-(2-phenylethenyl)-3-thiopyrano[2,3-b]pyrrol-6-yl-1,2,3,4-tetrazol-2-ium-2-yl]-2,3,4a,5,6,7,8,8a-octahydrophthalazine-1,4-dione chloride A824020 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 508.00 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
