2-phosphonobutane-1,2,4-tricarboxylic acid

Flash point

Administrative data

Endpoint:

flash point of flammable liquids

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the flash point is only relevant to liquids and low melting point solids

the study does not need to be conducted because the substance only contains volatile organic components with flash-points above 100°C for aqueous solutions

Justification for type of information:

2-phosphonobutane-1,2,4-tricarboxylic acid is a solid which is only available and marketed in a ca. 50% aqueous solution. The acid itself has a vapour pressure of 8.08e-9 Pa and is thus not volatile. Therefore, neither for the anhydrous solid form nor the aqueous solution (which contains no other volatile compounds than water) a flash point needs to be determined.
