UN Number 3342
Molecular weight 158.2g/mol
EINECS number 205-443-5
H.S. Code 293090.2000

Appearance White to light yellow crystalline solid powder or pellets.
Odor Slightly unpleasant odor.
Melting point 124^oC
Bulk density 1.225g/cm³
Active ingredient ≥ 90.0%
Solubility Highly soluble in water and alcohol; decomposes in acidic or high-temperature conditions.
Stability Less stable than longer-chain xanthates (e.g., potassium amyl xanthate) due to its smaller hydrophobic group.

It's wide range of uses in the flotation of metal sulphides ores.

Low cost and strong collecting ability, widely used in copper, molybdenum and zinche flotation process.

For gold and copper-gold recovery rate has obvious advantages for refractory copper-lead oxide ore.
