Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
4 -Dimethylaminopyridine (DMAP) is a white solid material which is manufactured as non-respirable prills or pastilles of greater than 600 micron diameter, in order to minimize potential inhalation by workers. It has a low vapour pressure and a relative density of 0.96. The substance is soluble in water, with a log Kow of 1.34. It is alkaline in solution, with a pH of greater than 10 (11.28 at the solubility limit) and a pKa of 10.14. At higher concentrations in solution, DMAP forms a nonahydrate (DMAP ▪ 9H2O) which perturbs the system, perhaps organizing the water molecules around itself. It melts at 115 °C, and does not auto-ignite.
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.
