About Palladium

Palladium (Pd), a soft, silvery-white metal and critical member of the Platinum Group Metals (PGM) family, is foundational to modern industrial chemistry, valued both as a precious metal asset & a peerless catalyst. In primary industrial form, Palladium 10% on Carbon (Pd/C) (CAS: 7440-05-3) is a heterogeneous supported...

Pharmaceutical Synthesis

(Debenzylation) Removal of Benzyl (Bn) protecting groups in complex API intermediates (e.g., cephalosporins, peptides) via Hydrogenolysis

Fine Chemical Production

(Hydrogenation) Selective reduction of nitro compounds to primary amines (a key step in dye/polymer/chemical precursor synthesis) and reduction of alkenes and alkynes

Environmental

(Dehalogenation) Preferred for the reductive dehalogenation of aromatic halides (removal of Halogen atoms by Hydrogen).

Separation Efficiency

As a heterogeneous catalyst, it is easily separated from the final product by simple filtration, reducing downstream purification costs for CDMOs

Detail 1

Store WET (wetted with water or appropriate solvent). NEVER allow the catalyst powder to dry out, as this is the condition that leads to spontaneous combustion in air.

Detail 2

Store Under Inert Gas (Nitrogen or Argon). This prevents oxidation and ignition, especially if the product is dry or contains residual hydrogen.

Detail 3

Store in a cool, dry, well-ventilated, and fire-resistant area. Keep away from any sources of ignition, heat, or hot surfaces.

Detail 4

Must be segregated from strong oxidizing agents, acids, bases, and alcohols (which can be easily ignited by dry Pd/C).
