Description
CATO supplies O8M467C50G 1228585-88-3 GS-9620 Vesatolimod [INN] Vesatolimod [USAN:INN] UNII-O8M467C50G 6(5H)-Pteridinone, 4-amino-2-butoxy-7,8-dihydro-8-((3-(1-pyrrolidinylmethyl)phenyl)methyl)- GS9620 GS 9620 Vesatolimod (CAS 1228585-88-3), a certified reference material (molecular formula C22H30N6O2, MW 410.51 g/mol) for analytical method development and quality control.
The molecular framework of O8M467C50G 1228585-88-3 GS-9620 Vesatolimod [INN] Vesatolimod [USAN:INN] UNII-O8M467C50G 6(5H)-Pteridinone, 4-amino-2-butoxy-7,8-dihydro-8-((3-(1-pyrrolidinylmethyl)phenyl)methyl)- GS9620 GS 9620 Vesatolimod (C22H30N6O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
