Chemical Structure
Description
Owing to a carbohydrate-derived structure, Ascorbic Acid Calcium Salt is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 215.19 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 Ascorbic Acid Calcium Salt (CAS 5743-27-1), a certified reference material (molecular formula C6H7O6Ca, MW 215.19 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.
CATO manufactures Ascorbic Acid Calcium Salt under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
