Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
non flammable (EU Method A.10, preliminary test )
no pyrophoricity (EU Method A.13, assessment of chemical structure)
no flammability on contact with water (EU Method A.12, assessment of chemical structure + simple experiment)
Key value for chemical safety assessment
- Flammability:
- non flammable
Additional information
In the preliminary test prodecure of EU Method A.10 2,2-[2-(3-butoxypropyl)-1,1-dioxo-1,2,4-benzothiadiazin-3-yI]-5’-tert-butyl-2-(5,5-dimethyl-2,4-dioxo-1,3-oxazolidin-3-yI)-2’-[(2-ethylhexyl)thio]acetanilide (UY-330) could not be ignited with the flame of a gas-burner. The substance melted and turned yellow (original colour: off-white) in contact with the ignition source. After removal of the flame, no propagation of combustion throughout the test substance pile was observed. Therefore the substance is not “highly flammable” according to the criteria as described in the method A.10 of EEC-Directive 92/69 EEC.
Based on experience in handling and use and the chemical structure pyrophoricity and flammability on contact with water are not to be expected.
Justification for classification or non-classification
The available data on flammability of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008 and are therefore conclusive but not sufficient for classification:
In the test according to EU Metod A.10 the test substance could not be ignited with a flame.
Based on the chemical structure and experience in handling and use, pyrophoricity and flammability on contact with water are not expected.
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.
