Executive summary:

The explosive properties of 2 -chloro-5 -chloromethylpyridine were tested according to EU test method A.14. As a sceening test the thermal stability according to OECD 113 was performed.

The determination of the thermal stability was carried out by differential scanning calorimetry (DSC). The test item and the standard material in closed glass crucibles were heated up from ambient temperature to the final temperature (500 °C) at a constant heating rate (3 K/min) in a defined atmosphere (nitrogen).

Thermal Sensitivity

The method involves heating the substance or preparation in a steel tube, with various degrees of confinement being provided by nozzle-plates with a diameter (2 mm) of orifice, to determine whether the substance or preparation is liable to explode under conditions of thermal stress.

Mechanical Sensitivity (Shock)

The method involves subjecting the substance or preparation to the shock of a falling hammer on a steel anvil. The test was performed with the powdered and sieved (< 500 µm) test item.

Mechanical Sensitivity (Friction)

The method involves subjecting the substance or preparation to friction between standard surfaces under specified conditions of load and relative motion. This test is restricted to solid and pasty substances or preparations. The test was performed with the powdered and sieved (< 500 µm) test item.

2-Chloro-5-chloromethylpyridine has no danger of explosion according to the explosive properties in the sense of the consolidated version of Council Directive 67/548/EEC Annex V, A. 14.
