TGA data show there were two thermal events resulting in weight loss associated with sample decomposition. These events occurred at

derivative peak values of 158 and 258 ⁰C and correspond to weight loss values of approx. 17% and 82.5%, respectively. A residue remained at 600 C accounting for 0.5 % of the material. The TGA thermograph is attached as Figure 1.

Table 1: Results of TGA Analysis

Overall Onset of Weight Loss (˚C)	Thermal Events (Exotherms)		%wt Residue at 600 °C
128	Derivative Peak (°C)	% wt Loss	0.5
	158	17.0
	258	82.5

Conclusions:

Analysis by TGA indicates the test substance decomposes before boiling. The test material’s weight loss associated with decomposition occurred at 158 and 258 degrees C.

Executive summary:

A thermogravimetric analysis, performed according to the ASTM E2550 -07 guideline, indicates the test substance decomposes before boiling.

The test material was heated under nitrogen up to 600^oC. Examination of the TGA curve shows two main thermal events (exotherms) at derivative peak values of 158 and 258^oC corresponding to weight loss values of approximately 17.0 and 82.5 %, respectively. The onset of weight loss occurred at approx. 128^oC. A residue, accounting for approx. 0.5 % of the test material remained at 600 ^oC.

Description of key information
