(2R,4S,5R,6R)-5-Acetamido-2,4-dihydroxy-6-[(1S,2R)-1,2,3-trihydroxypropyl]tetrahydro-2H-pyran-2-carboxylic Acid CAS 21646-00-4

Description

Owing to a carbohydrate-derived structure, an amide group, (2R,4S,5R,6R)-5-Acetamido-2,4-dihydroxy-6-[(1S,2R)-1,2,3-trihydroxypropyl]tetrahydro-2H-pyran-2-carboxylic Acid is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 309.27 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).

(2R,4S,5R,6R)-5-Acetamido-2,4-dihydroxy-6-[(1S,2R)-1,2,3-trihydroxypropyl]tetrahydro-2H-pyran-2-carboxylic Acid (CAS 21646-00-4), molecular formula C11H19NO9 and molecular weight 309.27 g/mol, is a CATO reference standard with documented purity and traceability.

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), (2R,4S,5R,6R)-5-Acetamido-2,4-dihydroxy-6-[(1S,2R)-1,2,3-trihydroxypropyl]tetrahydro-2H-pyran-2-carboxylic Acid 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.
