Primary Applications of Platinum on Carbon

Platinum on Carbon excels as a versatile, recoverable heterogeneous catalyst for selective reductions and functional group transformations in high-value chemical manufacturing.

1. Hydrogenation of Alkenes & Alkynes
   Enables efficient, selective reduction of carbon-carbon multiple bonds in complex molecules, ideal for pharmaceutical intermediates and fine chemical synthesis with minimal over-reduction.

2. Aromatic Ring Hydrogenation
   Catalyzes saturation of benzene rings and heterocycles under moderate conditions, producing cyclohexyl derivatives for agrochemicals, polymers, and performance chemicals.

3. Nitro Group Reduction
   Provides clean, high-yield conversion of aromatic and aliphatic nitro compounds to amines, a critical step in dye, pesticide, and API manufacturing.

4. Debenzylation & Hydrogenolysis
   Facilitates selective removal of benzyl protecting groups (Bn, Cbz, Bom) from alcohols, amines, and acids with excellent functional group tolerance in multistep synthesis.

5. Carbonyl & Imine Reduction
   Supports hydrogenation of ketones, aldehydes, and imines to alcohols or amines, offering superior selectivity in the presence of other reducible groups.

6. Hydrosilylation & Specialty Reactions
   Used in platinum-catalyzed addition of Si-H bonds to unsaturated substrates for organosilicon compounds and silicone polymer modifications.
