Name	CYANOGEN	EINECS	N/A
CAS No.	460-19-5	Density	1.076g/cm³
PSA	47.58000	LogP	0.03356
Solubility	1.51E+05 mg/L at 25℃	Melting Point	-27.9℃
Formula	C2N2	Boiling Point	°Cat760mmHg
Molecular Weight	52.0354	Flash Point	°C
Transport Information	N/A	Appearance	Colourless gas with pungent, almond-like odor
Safety	A poison by subcutaneous and possibly other routes. Moderately toxic by inhalation. Human systemic effects by inhalation: damage to the olfactory nerves and irritation of the conjunctiva. A systemic irritant by inhalation and subcutaneous routes. A human eye irritant. Very dangerous fire hazard when exposed to heat, flames (sparks), or oxidizers. To fight fire, stop flow of gas. Potentially explosive reaction with powerful oxidants (e.g., dichlorine oxide, fluorine, oxygen, ozone). When heated to decomposition or on contact with acid, acid fumes, water, or steam will react to produce highly toxic fumes of NO_x and CN⁻. See also other cyanogen entries and CYANIDE.	Risk Codes	11-23-50/53
Molecular Structure		Hazard Symbols	Flammable limits in air 6–32%. Store away from light and heat. A very toxic material. TLV: 10 ppm.
Synonyms	Cyanogen(C2N2) (8CI); Carbon nitride (C2N2); Cyanogen; Dicyan; Dicyanogen;Nitriloacetonitrile; Oxalic acid dinitrile; Oxalonitrile; Oxalyl cyanide	Article Data	493
