Description of key information
Yttrium trichloride hexahydrate is a white to yellowish crystalline powder with pungent odour. This is confirmed in the safety data sheet from a manufacturer (TIAG, 2016) as well as in a study report on melting point in which the test item appearance upon receipt in the testing laboratory is reported (Demangel, 2017).
Key value for chemical safety assessment
- Physical state at 20°C and 1013 hPa:
- solid
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
