Guanosine 3,5-cyclic Monophosphorothioate, β-Phenyl-1,N2-etheno-8-bromo-, Rp-Isomer, Sodium Salt - CAS 172806-20-1 - Calbiochem CAS 172806-20-1

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.

CATO supplies Guanosine 3,5-cyclic Monophosphorothioate, β-Phenyl-1,N2-etheno-8-bromo-, Rp-Isomer, Sodium Salt - CAS 172806-20-1 - Calbiochem (CAS 172806-20-1), a certified reference material (molecular formula C18H15BrN5O6PS, MW 540.28 g/mol) for analytical method development and quality control.

Guanosine 3,5-cyclic Monophosphorothioate, β-Phenyl-1,N2-etheno-8-bromo-, Rp-Isomer, Sodium Salt - CAS 172806-20-1 - Calbiochem (C18H15BrN5O6PS) contains a flavonoid core, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
