If you’re researching peptide synthesis or developing modified biomolecules, Fmoc-4-Amino-L-Phenylalanine (CAS 95753-56-3) is likely a critical building block in your workflow. However, sourcing high-purity, reliable batches of this specialty amino acid derivative can be challenging. With so many suppliers online, how do you know which ones are trustworthy—and which could derail your experiments with subpar products?
In this guide, we’ll simplify your search by revealing five vetted suppliers of Fmoc-4-Amino-L-Phenylalanine (FMOC-PHE(4-NH2)-OH), along with actionable tips to avoid scams and secure the best value.
Why Choosing the Right Supplier Matters
Fmoc-4-Amino-L-Phenylalanine is a sensitive compound used in advanced peptide synthesis. Even minor impurities (e.g., free amino groups, residual solvents) can compromise coupling efficiency or final product integrity. Here’s what’s at stake when selecting a supplier:
- Purity Standards: ≥98% purity is non-negotiable for reproducible results.
- Certifications: Suppliers should provide CoA (Certificate of Analysis) and MSDS documentation.
- Packaging: Moisture-resistant, light-protected packaging ensures stability during shipping.
- Customer Support: Responsive technical teams can address synthesis-related queries.
Cutting corners here risks wasted time, funding, and experimental outcomes. Let’s explore your safest options.
