Description
CATO supplies 160385-87-5 guanosine,8-[(4-chlorophenyl)thio]-, cyclic 3',5'-[(s)-hydrogen phosphorothioate] (9ci) (CAS 160385-87-5), a certified reference material (molecular formula C16H15ClN5O6PS2, MW 503.88 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine substitution, 160385-87-5 guanosine,8-[(4-chlorophenyl)thio]-, cyclic 3',5'-[(s)-hydrogen phosphorothioate] (9ci) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 503.88 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
