Description of key information

GLP-study according to OECD 109, using gas comparison pycnometer method, relative density (at 20°C compared to water at 4°C) D = 1.64.

Supporting information, handbook data, 2-oxoglutaric acid D = 1.0 g/cm³

Key value for chemical safety assessment

Relative density at 20C:
