Description of key information

According to Annex VII No. 7.4 Column 2 of Regulation (EC) No. 1907/2006 (REACH) the study has not to be conducted if the substance is a gas. In this case an estimation based on molecular weight and the Ideal Gas Law shall be made. According to Annex I No. 1.0 chlorodifluoromethane fulfills the criteria of a gas so no experimental information information is requested. 

Key value for chemical safety assessment

Relative density at 20C:
3.595

Additional information

According to Annex VII No. 7.4 the

density of chlorodifluoromethane was calculated on base of the molar mass and the molar volume of an ideal gas at 20 °C (293.15 K) and gave a value of 3.5947 kg/m³.
