N-((Tetrahydrofuran-2-yl)methyl)-2-((3-(p-tolyl)-3H-[1,2,3]triazolo[4,5-d]pyrimidin-7-yl)thio)acetamide (CAS 863459-66-9), molecular formula C18H20N6O2S and molecular weight 384.46 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, N-((Tetrahydrofuran-2-yl)methyl)-2-((3-(p-tolyl)-3H-[1,2,3]triazolo[4,5-d]pyrimidin-7-yl)thio)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 384.46 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.
As a certified reference material (CRM), N-((Tetrahydrofuran-2-yl)methyl)-2-((3-(p-tolyl)-3H-[1,2,3]triazolo[4,5-d]pyrimidin-7-yl)thio)acetamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
