Grubbs’ Catalyst 2nd Generation (CAS 246047-72-3) is a cornerstone of modern organic synthesis, but its performance hinges on one critical factor: purity. Low-quality catalysts can lead to failed reactions, inconsistent yields, and wasted resources. In this post, we’ll reveal the secret suppliers trusted by top labs for high-purity Grubbs’ Catalyst 2nd Generation and explain how to ensure you’re getting the best product for your research.
Why High Purity Matters
1. Reaction Efficiency
Impurities in Grubbs’ Catalyst can:
- Reduce yields by 20–50%.
- Slow reaction kinetics, increasing synthesis time.
- Deactivate the catalyst, requiring higher loadings.
2. Reproducibility
High-purity catalyst ensures consistent results across experiments, which is critical for:
- Academic publications.
- Patent applications.
- Scale-up processes.
3. Cost Savings
While high-purity catalyst may have a higher upfront cost, it reduces:
- Waste disposal fees.
- Reagent overuse.
- Repeat experiments.
5 Red Flags of Low-Quality Suppliers
1. Missing Certificates of Analysis (CoA)
Legitimate suppliers provide batch-specific CoAs with:
- HPLC/NMR data verifying ≥99% purity.
- Trace metal analysis (e.g., ruthenium content).
2. No Safety Data Sheets (SDS)
SDS documents are essential for regulatory compliance and safe handling.
3. Unrealistically Low Prices
Suppliers offering prices below $150/gram often cut corners on synthesis or testing.
4. Poor Packaging
High-purity catalyst must be sealed under argon in amber vials to prevent degradation.
5. Lack of Licensing
Grubbs’ Catalyst is patented – unlicensed suppliers risk legal action and product confiscation.

How to Verify High Purity
1. Request a CoA
Ensure the CoA includes:
- Batch number and synthesis date.
- Purity data (HPLC/NMR).
- Trace metal analysis.
2. Inspect Packaging
High-purity catalyst should be:
- Sealed under argon in amber vials.
- Labeled with CAS 246047-72-3 and storage instructions.
3. Test the Catalyst
Run a small-scale reaction to verify performance before committing to bulk orders.
