Chemical Structure
Description
The occurrence of D-Galactono-1,4-lactone is closely related to a carbohydrate-derived structure in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies D-Galactono-1,4-lactone (CAS 2782-07-2), a certified reference material (molecular formula C6H10O6, MW 178.14 g/mol) for analytical method development and quality control.
Owing to a carbohydrate-derived structure, D-Galactono-1,4-lactone is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 178.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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-Galactono-1,4-lactone 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.
