Title:
Aminopyrazol: Determination of the Relative Density
Purpose:
The purpose of the study was to determine the relative density of Aminopyrazol at a specific temperature by means of a gas comparison pycnometer.
Guidelines/Recommendations: This study was based on the procedures indicated by the following internationally accepted guidelines and recommendations:
-Commission Regulation (EC) No.440/2008 laying down test methods pursuant to Regulation (EC) No.1907/2006 of the European Parliament and of the Council on the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) (originally published as Council Regulation (EC) No.440/2008, corrigendum according to Official Journal of the European Union (EN) dated June 3, 2008, L 143/55), Annex, Part A, A.3.: “Relative Density”, Official Journal of the European Union, L 142, Volume 51, 31 May 2008
-Organisation for Economic Co-operation and Development (OECD), OECD Guidelines for Testing of Chemicals, Guideline No. 109, “Density of Liquids and Solids”, adopted October 02, 2012
-Product Properties Test Guideline OPPTS 830.7300 of the United States Environment Protection Agency (EPA), June 2002
Results:
The relative density of Aminopyrazol was determined using the gas comparison method at a temperature of 20 °C ± 1 °C.
The determination of the relative density was performed by three-fold measurements of two independent test item samples. The individual readings are summarised in Table 1.
The density of Aminopyrazol was determined to be 1.335 g/cm³ (= 1335 kg/m³) at 20 °C ± 1 °C.
Conclusion:
In conclusion, the relative density of Aminopyrazol was determined to be 1.335. This study is classified acceptable and satisfies the guideline requirements for relative density studies.
