About Lead sulphide

Lead sulphide is a main-group metal compound carrying the CAS registry number 1314-87-0, specified at ≥98% purity. Its molecular formula is PbS and its molecular weight is 239.0 g/mol. Systematically, it is named lead(2+) sulfide. Alternative names: Lead(II) sulfide and Lead monosulfide.

It is supplied as green to yellow to grey powder to crystals. Reported physical data include a density of 7.5 g/mL at 25 °C. Keep the container tightly sealed and store it in a cool, dry area. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Key uses span dyes and pigments manufacture and electronics and thin films. It is used across academic and industrial research.

Available in 100 g, 500 g and 4 x 25 kg packs, Lead sulphide is dispatched with a Certificate of Analysis (COA) to destinations worldwide.
