Chemical Structure

Adenosine 3’,5’-cyclic monophosphothioate Sp-isomer sodium salt CAS 71774-13-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 446.46 g/mol gives Adenosine 3’,5’-cyclic monophosphothioate Sp-isomer sodium salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Adenosine 3’,5’-cyclic monophosphothioate Sp-isomer sodium salt (CAS 71774-13-5), molecular formula C10H12N5O5PSC6H15N and molecular weight 446.46 g/mol, is a CATO reference standard with documented purity and traceability.

Adenosine 3’,5’-cyclic monophosphothioate Sp-isomer sodium salt (C10H12N5O5PSC6H15N) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

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.

As a certified reference material (CRM), Adenosine 3’,5’-cyclic monophosphothioate Sp-isomer sodium salt meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
