Grubbs’ Catalyst 2nd Generation (CAS 246047-72-3) is indispensable for advanced organic synthesis, but sourcing it legally and safely can be a minefield. Counterfeit products, unverified suppliers, and regulatory pitfalls abound. In this guide, we’ll expose 5 trusted suppliers that guarantee authenticity, compliance, and reliability – so you can focus on groundbreaking science, not supply chain headaches.
Why Buying Legally Matters: Risks of Unverified Suppliers
1. Counterfeit Catalysts
Illegally sourced catalysts often lack proper documentation or contain impurities, leading to:
- Failed reactions (e.g., incomplete ROMP or metathesis).
- Contaminated end products (critical in pharmaceuticals).
- Regulatory violations (e.g., OSHA or REACH non-compliance).
2. Hidden Costs
“Cheap” suppliers may skip essential steps like:
- Inert packaging (leading to rapid degradation).
- Batch testing (inconsistent purity).
- Licensing fees (risking intellectual property disputes).
3. Legal Liability
Using uncertified catalysts in commercial R&D or manufacturing can void patents or trigger audits.

How to Verify a Supplier’s Legitimacy
1. Check Certifications
Legitimate suppliers provide:
- CAS 246047-72-3 on all documentation.
- Certificates of Analysis (CoA) with HPLC/NMR data.
- Safety Data Sheets (SDS) compliant with OSHA/GHS.
2. Review Third-Party Testing
Ask for:
- Independent lab validation reports.
- Customer testimonials (e.g., university partnerships).
3. Confirm Licensing
Grubbs’ Catalyst is patented – ensure suppliers pay royalties to avoid legal issues. KiloBio holds full licensing rights for commercial distribution.

3 Red Flags to Avoid When Buying Online
- Missing CAS Numbers
Suppliers omitting CAS 246047-72-3 likely sell generic or counterfeit catalysts. - No Batch-Specific CoAs
Always insist on recent CoAs – outdated reports suggest stagnant inventory. - “Too Fast” Shipping Claims
Authentic catalysts require careful packaging (argon-sealed, cold-packed). Avoid suppliers promising overnight delivery without proper protocols.
