CAS No. 7631-86-9, EC Number 231-545-4. Physicochemical Information Melting Point 1710 °C pH value 7 (100 g/l, H₂O, 20 °C) (slurry) Bulk density 200 - 800 kg/m3 Toxicological Information LD 50 dermal LD50 Rabbit > 5000 mg/kg Safety Information according to GHS Storage class 10 - 13 Other liquids and solids WGK NWG not water endangering Disposal 32 Chromatographic residues: Aggressive, explosive (e.g. peroxides) or toxic substances in chromatographic layers or sorbents must be eliminated using suitable methods (washing out, elution) prior to disposal. The solvents used for elution can in many cases be reutilized. Larger quantities of sorbents (e.g. from columns) should be freed from solvents (filtration, drying) and packed into rip-resistant plastic sachets; container I. TLC carrier materials and columns should be disposed of together with the corresponding waste materials (aluminium, glass, plastic); container K.
