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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2017
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- other: OECD 113 (TGA)
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Key result
- Decomposition:
- yes
- Remarks:
- The physical modification of the substance starts at 240° even if the real decomosition is measured at 270°ing
- Decomp. temp.:
- ca. 270 °C
- Remarks on result:
- other: measured by DSC
- Conclusions:
- The substance Butanedioic acid, 2,3-dihydroxy- [R-(R*,R*)]-, C12-13-branched alkyl esters shows a modification of the physical properties at 240°, no boiling point below. The decomposition of the substance has been determined at 270°C by DSC technique.
Reference
experimental set-up:
Parameter Value Instrument Hitachi STA 7200
Gas (flow) Air (200 mL min-1)
Initial temper.(°C) 30
Final temper.(°C) 460
Temper. Gradient (°C min-1) 10
Pan material Al (open)
Balance resolution (mg) ±0.001
Sample weight (mg) 9.307
Pressure ~ 0.1 MPa
Description of key information
The measuerment of the boiling point can not be determined because the substance Butanedioic acid, 2,3-dihydroxy-[R-(R*,R*)]-, C12-13-branched alkyl esters decomposes at 270°C
Key value for chemical safety assessment
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
