Chemical Structure

Rebaudioside A CAS 58543-16-1 chemical structure

Description

As a certified reference material (CRM), Rebaudioside A 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.

Rebaudioside A (CAS 58543-16-1), molecular formula C44H70O23 and molecular weight 967.01 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Rebaudioside A is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 967.01 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
