Chemical Structure
Description
CATO supplies 5-Phosphoryl-(3-amino-3-deoxyguanylyl)-(3-5)-3-amino-3-deoxycytidine (CAS 109679-54-1), a certified reference material (molecular formula C19H28N10O13P2, MW 666.43 g/mol) for analytical method development and quality control.
Structurally, 5-Phosphoryl-(3-amino-3-deoxyguanylyl)-(3-5)-3-amino-3-deoxycytidine (C19H28N10O13P2) contains a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 666.43 g/mol, it falls into the high-molecular-weight range. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
