Chemical Structure

Primary Applications of Platinum on Carbon

Platinum on Carbon is the workhorse heterogeneous catalyst for selective hydrogenation and related transformations in high-value chemical manufacturing.

1. Hydrogenation of Alkenes & Alkynes
    Provides fast and selective reduction of C=C and C≡C bonds in complex molecules, enabling clean synthesis of pharmaceutical intermediates and natural product derivatives with minimal over-reduction.

2. Aromatic Ring Hydrogenation
    Efficiently saturates benzene rings and heteroaromatics under moderate pressure and temperature, producing valuable cyclohexane-based building blocks for agrochemicals, polymers and performance materials.

3. Nitro Group Reduction to Amines
    Delivers high-yield, clean conversion of aromatic and aliphatic nitro compounds to primary amines, a key transformation in dyes, pesticides and active pharmaceutical ingredient manufacturing.

4. Debenzylation & Protecting Group Removal
    Enables selective hydrogenolysis of O-benzyl, N-Cbz and related protecting groups with excellent functional group tolerance, critical for multi-step synthesis in medicinal chemistry.

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

6. Fine Chemical & API Manufacturing
    Widely applied in GMP processes for the reduction steps of active pharmaceutical ingredients, offering scalability, easy catalyst removal and high reproducibility.

• Optimized Metal Dispersion & Activity
   Advanced impregnation technology ensures uniform Pt particle size and high active surface area for maximum turnover frequency and product selectivity.

• Custom Catalyst Formulations
   Tailored Pt loadings, support types, reduction states and additives to precisely match your substrate, solvent system and reaction conditions.

• Consistent Batch-to-Batch Reproducibility
   Rigorous in-house testing (ICP, BET, XRD, activity testing) guarantees low variation and predictable scale-up performance.

• Secure Platinum Supply & Traceability
   Responsible sourcing of platinum with full traceability, inventory buffering and recycling programs to mitigate price volatility and ensure long-term availability.

• Technical & Regulatory Support
   Expert guidance on catalyst activation, poisoning mitigation, recycling, and full documentation (COA, REACH, SDS) for seamless integration into GMP and fine chemical operations.
