Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The endpoint is waived, existing reported/calculated data cannot be verified as accurate, and as the substance is an onsite isolated intermediate, no testing is necessary.
The vapour pressure of citraconic anhydride is reported as 133 Pa at 47.1 °C and calculated as ca. 24 Pa @ 25 °C.
Key value for chemical safety assessment
Additional information
Three data from handbooks, two of them orginating from the same reference: Stull, Ind. Eng. Chem.,39,517(1947), the third one probably too, because exactly the same temperature ( 47.1 °C) and pressure(1 mmHg = 133 Pa) is mentioned.
See:
616-02-4, Vapour pressure, Lide, D.R. (ed).,1993, WoE
616-02-4, Vapour pressure, Shuzo Ohe, 1976, WoE

Calculated vapour pressure is ca. 24 Pa @ 20 oC (ACD and EpiSuite).
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.
