L-Dehydro Ascorbic Acid CAS 490-83-5

Description

Compared with other compounds in its class, the molecular weight of 174.11 g/mol gives L-Dehydro Ascorbic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies L-Dehydro Ascorbic Acid (CAS 490-83-5), a certified reference material (molecular formula C6H6O6, MW 174.11 g/mol) for analytical method development and quality control.

Based on its molecular formula C6H6O6, L-Dehydro Ascorbic Acid contains a carbohydrate-derived structure; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 174.11 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), L-Dehydro Ascorbic 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.
