EC number: 219-863-1 | CAS number: 2554-06-5
Melting point (2,4,6,8-tetramethyl-2,4,6,8-tetravinylcyclotetrasiloxane): -55.6±0.5°C (OECD 102)e
Three reliable studies are available for the melting point of Vi4 -D4. A melting point value of -55.6±0.5°C was obtained for the substance in accordance with EU Method A.1 and OECD Guideline 102 but not in compliance with any known quality system. The result is considered to be reliable and selected as key study.
This result is supported by measured melting point values for Vi4 -D4 of -43.5°C and -42.7°C which were determined using relevant methods.
All available studies report that the melting point of the substance is <-20°C.
