Endpoint summary
Administrative data
Description of key information
Appearance:
The substance is an odourless, beige, crystalline solid at 20 ºC and 1013 hPa.
(Source: Internal company data)
Melting point:
The melting point was determined to be 60.8°C, using the capillary tube method.
(Source: GLP-report)
Boiling point:
The boiling point was found to be > 375°C at atmospheric pressure, using the Siwoloboff method.
(Source: GLP-report)
Relative density:
The relative density was determined to be 1.01, using the pycnometer method.
(Source: GLP-report)
Particle size distribution:
Due to the size and form of the crystalline test material, the determination of the particle size distribution by sieving analysis or laser diffraction was not possible.
(Source: Expert assessment)
Vapor pressure:
The vapour pressure of LZ 53 was estimated based on theGrain-Watson (GW) equation. At 25°C, a vapour pressure of 1.45 x 10 Exp-07 Pa was calculated.
(Source: GLP-report)
Partition coefficient:
The log Pow n-octanol/water was determined to be 5.68 at 23.3°C, using the flask shaking method.
(Source: GLP-report)
Water solubility:
The solubility of M-DIPA in water was determined to be 0.488 µg/L at 23°C.
(Source: GLP-report)
Surface tension:
Substance is poorly soluble in water (< 1 mg/L), therefore test was waived.
(Source: Expert assessment)
Flash point:
Not applicable, solid substance. The flammability test was performed instead.
(Source: Expert assessment)
Auto flammability:
No self-ignition was observed up to the melting point of 61°C at atmospheric pressure.
(Source: GLP-report)
Flammability:
The substance is not flammable. The molecular structure of the substance does not contain groups that indicate potential reactivity with water or pyrophoric properties and handling of the substance indicates that this is the case.
(Source: Expert assessment)
Explosiveness:
Based on chemical structure and information on handling and use the substance was considered non-explosive. Experimental determination was waived.
(Source: Expert assessment)
Oxidizing properties:
From the assessment of the chemical structure it was established that the test substance would not have oxidizing properties.
