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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: - | CAS number: -
Auto flammability
Administrative data
- Endpoint:
- relative self-ignition temperature (solids)
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is a solid having a melting point <= 160°C
Cross-reference
- Reason / purpose for cross-reference:
- data waiving: supporting information
Reference
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2010
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7200 (Melting Point / Melting Range)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- GLP compliance:

- Key result
- Melting / freezing pt.:
- 332.6 - 336.5 K
- Atm. press.:
- 1 013 hPa
- Decomposition:
- no
- Sublimation:
- no
- Conclusions:
- Reaction product of 2-hydroxybenzoic acid, styrene and oxozinc has a melting range of 59.4 to 63.3°C (332.6 to 336.5 K). These values are the means of two independent determinations.
- Executive summary:
Values Main Study
Melting point/range Begin End 1st determination 59.6 °C (332.8 K) 63.3 °C (336.5 K) 2nd determination 59.2 °C (332.4 K) 63.2 (336.4 K) Result Test Item
The means of both determinations give the following values for the melting range:
Melting point: 59.4 to 63.3°C (332.6 to 336.5 K) Standard deviation: 0.28 (begin); 0.07 (end) Estimated accuracy: ± 0.4°C The test item Reaction product of 2-hydroxybenzoic acid, styrene and oxozinc showed a melting range, no melting point. As the test item consists of a mixture, this is considered as normal. No observations were made which might cause doubts on the validity of the study out-come. Therefore, the result of the study is considered valid.

Applicant's summary and conclusion
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.
