Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- read-across based on grouping of substances (category approach)
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- Thiobis Propanoic Acid Derivatives
The category covers thiiodipropionates that are symmetrically esterified by two linear aliphatic groups ranging in size from C10 to C24
The justification for the category is based on the expectation that the close structural similarity should result in properties that are either similar or follow a pattern that correlates with changes in the molecular weights of the compounds. The category members are high-molecular weight dithiopropionate esters that differ only in the chain length of the dialkyl ester functions and are expected to follow a regular pattern for all endpoints.
Based on the structures and molecularweights of the category members, as well as available data on category members, The predictive methods and extrapolation and interpolation of data within the category are acceptable. Data provided by other sources also demonstrate that these compounds generally have mammalian toxicities that are similar (e.g., acute oral LD 50, acute irritation thresholds, and genotoxicities) or follow a pattern that parallels changes in molecular weight (e.g., repeated-dose NOAEL). - Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Key result
- Boiling pt.:
- >= 257 - <= 258
- Atm. press.:
- 1 013 hPa
- Decomposition:
- no
- Decomp. temp.:
- > 300 °C
- Conclusions:
- The test item Propanoic acid, 3,3’-thiobis-, di-C16-22-alkyl esters has a boiling point of range of 257 – 258 °C corrected to normal atmospheric pressure (1013 hPa) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.2. and OECD Test Guideline 103 (1995).

Additional information
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).
