Description of key information

Solubility In Organic Solvent  According to “ANNEX IX- STANDARD INFORMATION REQUIREMENTS FOR SUBSTANCES MANUFACTURED OR IMPORTED IN QUANTITIES OF 100 TONNES OR MORE, study for Stability in organic solvents and identity of relevant degradation products is only required if stability of the substance is considered to be critical.  Solvents are substances that are capable of dissolving or dispersing one or more other substances. Organic solvents are carbon-based solvents (i.e., they contain carbon in their molecular structure).  From the compositional description and the structural formula given, it can be concluded that this substance S-allyl O-pentyl dithiocarbonate is stable in organic solvents. There are no functional groups or other structural alerts present that would indicate that this substance should be reactive or give rise to any instability under routine storage conditions or testing conditions in general.  This reality is furthermore confirmed by long term handling experience in addition to observations made during subsequent downstream formulating and blending operations where this substance is also observed to be very stable.   It should be noted that this substance is not completely soluble in some very polar low molecular weight organic solvents (egs. alcohols, esters, ketones, and ethers). However, this is not the result of substance instability, and no reactions between these solvents and the functional groups present in this substance would be expected.  Its functional groups indicate no solubility in common organic solvents. Solubility in organic solvents is not considered critical. (Ref. 1)  Therefore testing for solubility in organic solvents does not need to be performed.     Ref. 1) European Chemicals Agency (ECHA), Guidance for the implementation of REACH, Guidance on information requirements and chemical safety assessment, Chapter R.7a: Endpoint specific guidance, May 2008, pages 168-171.
