Chemical Structure
Description
Owing to a carbohydrate-derived structure, D-Ascorbic Acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 176.12 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).
CATO supplies D-Ascorbic Acid (CAS 10504-35-5), a certified reference material (molecular formula C6H8O6, MW 176.12 g/mol) for analytical method development and quality control.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
