Chemical Structure
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.
Guanosine 5'-phosphate disodium salt hydrate (CAS 146894-16-8), molecular formula C10H12N5O8PNaH2O and molecular weight 402.21 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carbohydrate-derived structure, an amide group, a phosphate ester group, Guanosine 5'-phosphate disodium salt hydrate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 402.21 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
