(2R,3R,4S,5R,6S)-2-(azidomethyl)-6-methoxytetrahydro-2H-pyran-3,4,5-triyl triacetate CAS 21893-05-0 chemical structure

Description

The occurrence of (2R,3R,4S,5R,6S)-2-(azidomethyl)-6-methoxytetrahydro-2H-pyran-3,4,5-triyl triacetate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(2R,3R,4S,5R,6S)-2-(azidomethyl)-6-methoxytetrahydro-2H-pyran-3,4,5-triyl triacetate (CAS 21893-05-0), molecular formula C13H19N3O8 and molecular weight 345.31 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (2R,3R,4S,5R,6S)-2-(azidomethyl)-6-methoxytetrahydro-2H-pyran-3,4,5-triyl triacetate (C13H19N3O8) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 345.31 g/mol, it falls into the moderately-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.

As a certified reference material (CRM), (2R,3R,4S,5R,6S)-2-(azidomethyl)-6-methoxytetrahydro-2H-pyran-3,4,5-triyl triacetate meets the metrological traceability requirements of ISO/IEC 17025 laboratories.
