EC number: 218-212-9
CAS number: 2082-59-9
The test item does not contain any functional groups which can be
protonated or deprotonated significantly in aqueous solution.
With the computer program ACD/pKa DB ( Advanced Chemistry Development
Inc., Toronto, Canada) a pKa value could not be calculated.
Therefore, the substance is to be considered a neutral molecule in the
pH range 2 ¿ 10, which is of relevance for aqueous biological systems.
