Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 892-49-9 O532QJ0GH4 Arabinosyl-6-mercaptopurine 9-beta-D-Arabinofuranosyl-1,9-dihydro-6H-purine-6-thione 9-(beta-D-Arabinofuranosyl)-9H-purine-6-thiol 9H-Purine-6-thiol, 9-beta-D-arabinofuranosyl- 6H-Purine-6-thione, 9-beta-D-arabinofuranosyl-1,9-dihydro- (9CI) ARA-6MP beta-D-Arabinofuranosyl-6-mercaptopurine Arabinofuranosyl-6-mercaptopurine 9beta-Arabinofuranosyl-9-H-purine-6-thiol, D- 9-beta-D-Arabinofuranosyl-9H-purine-6-thiol 6MP-Arabinoside beta-D-Arabinosyl-6-mercaptopurine Ara-MP beta-Ara-6-MP BRN 5297846 EINECS 212-968-3 NSC-406021 6-Thio-9-beta-D-arabinofuranosylpurine NSC 406021 UNII-O532QJ0GH4 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 284.29 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.
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.
