Two TGD-approved handbooks agree that the notional solid structure has a melting point of 131°C (reported as D-gluconic acid).
Key value for chemical safety assessment
Additional information
Information concerning melting/freezing point of 50% aqueous solution of gluconic acid substance was reported as D-gluconic acid and was sourced from two separate handbooks. Merck Index: An Encyclopedia of Chemicals, Drugs, and Biologicals (14th Ed.) and CRC Handbook of Chemistry and Physics (81st Ed.), which are known to contain peer-reviewed data of Klimisch-2 reliability state that D-gluconic acid has a melting point of 131°C (corresponding to 404.15 K).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
