CAS number: 2432-99-7
Based on the available data on its physical and chemical properties,11
-aminoundecanoic acid is a white crystalline powder (diameter of
particles between 5 and 70 µm) with a melting point of
approximately 191°C at normal pressure and a relative
density of around 1.17 at 26°C. No boiling point is
available because there seems to be decomposition or polycondensation of
11 -aminoundecanoic acid before boiling. The vapour pressure is
estimated to be very low (estimation by calculation between
3.85E-02Pa and 2.07E-07
is considered as moderately soluble in water based on a water
solubility of 800 mg/L, and to have a low potential for
bioaccumulation based on a calculated logKow value of -0.16.
Its dissociation constants are as follows: pKa1 (amine) = 10.8 -11.15
and pKa2 (carboxylate) = 4.45 - 4.65.
Besides, 11 -aminoundecanoic acid has been shown to be non flammable
(EU method A10) and, by deposition on hot surfaces, to not flame
spontaneously up to 360°C and to decompose at temperature below
240°C. Based on its chemical structure, 11-aminoundecanoic acid is NOT
expected to be explosive nor to have oxidising properties.
