Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The MMAD (Mass Median Aerodynamic Diameter < 100 μm) has a value of 3.12 μm as spherical particles.
Additional information
According to OECD guideline 110, the particle size distribution of 3-Hydroxy-2-(3-hydroxy-2-quinolinyl)-1H-inden-1-one was determined by scanning electron microscopy method for the sieved fraction (< 100 µm, 7.40% of total sample) and presented on the basis of calculated mass fractions. The median diameter was 3.12 µm with the main fraction of 67.1% distributing in the range of 4 - 10 µm; and hence the tested 3-Hydroxy-2-(3-hydroxy-2-quinolinyl)-1H-inden-1-one particles with sieved size smaller than 100 µm are dominated by thoracic fraction as defined in EN 481.
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.
