Description of key information
Additional information
Penta-PSCA is a brown viscous liquid.
According to OECD102 study the melting point of Penta-PSCA is -8 ± 3°C.
According to OECD103 study the boiling point of Penta-PSCA is 347 ± 30°C (decomposes on boiling) at 101.9 kPa.
According to OECD109 study the density of Penta-PSCA is 1.0102 ±0.0002 g/cm³ at 20°C and the relative density is D420 = 1.01.
The vapour pressure of Penta-PSCA is 1.0 Pa at 20 °C.
According to OECD107 study the log pow of Penta-PSCA is 3.64.
According to OECD105 study the water solubility of Penta-PSCA is 0.23 g/L at 20°C.
According to ISO 4311 the critical micelle concentration of Penta-PSCA is 0.23 ± 0.11 g/L at 20°C. The critical micelle concentration is the appropriate parameter describing water solubility of surface active materials.
According to OECD105 study Penta-PSCA is miscible with n-octanol at every ratio.
For substances that are completely miscible with octanol, the numerical value of the octanol solubility should be derived from the density. Based on that the n-octanol solubility of Penta-PSCA is 1010.2 g/l.
According to OECD115 study the surface tension of Penta-PSCA is 37.2 ± 0.1 mN/m at a concentration of 90% of the saturation concentration at 25°C.
According to EU A.9 study the flash point of Penta-PSCA is 113±2°C at 101.9 kPa.
According to EU A.15 study the auto flammability of Penta-PSCA is 290 °C.
There are no structural alerts within Penta-PSCA and great experience in handling and use give evidence that no Pyrophoricity and Flammability on contact with water properties give any concern. For liquids the Flammability is described by the Flash Point. The Flash Point of the substance is 113±2°C.
Penta-PSCA is a is considered to have no explosive properties as there are no chemical groups associated with explosive properties present in the molecule.
Penta-PSCA is a is considered to have no oxidising properties as there are no halogen or oxygen atoms bond to nitrogen or oxygen.
Penta-PSCA is a is considered to be stable in organic solvents.
The pKa values of Penta-PSCA at 25 °C are:
pKa1 (COO- + H+ ⇌ COOH) : 4.74 ± 0.10
pKa2 (R3NH+ ⇌ R3N + H+) : -1.60 ± 0.40
According to OECD114 study the viscosity of Penta-PSCA is 16200 ± 400 mPa.s (dynamic, 20°C) / 2050 ± 50 mPa.s (dynamic, 40°C).
