Chemical Structure

Guanosine-13C,15N2 ·X Hydrate CAS 197227-95-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 286.22 g/mol gives Guanosine-13C,15N2 ·X Hydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Guanosine-13C,15N2 ·X Hydrate (CAS 197227-95-5) is a high-purity analytical reference standard with the molecular formula C9[13C]H13N3[15N]2O5 and a molecular weight of 286.22 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Guanosine-13C,15N2 ·X Hydrate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 286.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
