Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key data is available for Methylcyclopentane. Additionally, supporting data is also available for structural analogues hexane, 2-methylpentane, and 3-methylpentane, and this data is used for read across to Methylcyclopentane.

Data on physical properties were obtained from a number of secondary sources. The data in these secondary sources are based on a critical evaluation of peer-reviewed data and the selected values are considered to be reliable and representative of the property under investigation. Information in the review process was documented in the introduction of the source. The use of Klimisch codes (Klimischet al., 1997), was extended to these secondary sources and a reliability code of (2) valid with restrictions was assigned when using the authoritative secondary source. Proprietary data has also been used and this has been reviewed and assessed for reliability using klimisch codes. Where proprietary data has been considered reliable it has been given a reliability code of (2)valid with restrictionsand has been used in the assessment.

The reported boiling point of methylcyclopentane is 72°C.The calculated boiling point of methylcyclopentane is 80.34°C and the flashpoint is <0°C. According to the CLP legislation (2008) a substance with flash point <23°C and a boiling point >35°C is classified as a Category 2 flammable liquid.
