Chemical Structure
Description
The occurrence of D-Galacturonic acid is closely related to a carbohydrate-derived structure in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
D-Galacturonic acid (CAS 685-73-4), molecular formula C6H10O7 and molecular weight 194.14 g/mol, is a CATO reference standard with documented purity and traceability.
D-Galacturonic acid (C6H10O7) contains a carbohydrate-derived structure. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), D-Galacturonic 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.
