Fmoc-4-Amino-L-Phenylalanine Suppliers Compared: Who Offers the Best Purity & Price?

For researchers and pharmaceutical developers, sourcing high-quality Fmoc-4-Amino-L-Phenylalanine (CAS 95753-56-3) is critical for successful peptide synthesis. However, navigating the crowded marketplace of suppliers can be overwhelming. With claims of “highest purity” and “lowest prices” flooding the industry, how do you separate fact from marketing hype?

In this comprehensive comparison, we evaluate five leading suppliers of Fmoc-4-Amino-L-Phenylalanine (FMOC-PHE(4-NH2)-OH) based on verified purity standards, pricing transparency, certifications, and customer feedback. Whether you’re procuring grams for academic research or kilograms for industrial-scale production, this guide will help you choose the best partner for your needs.

Why Supplier Selection Matters for FMOC-PHE(4-NH2)-OH

Fmoc-4-Amino-L-Phenylalanine is a finicky reagent. Even minor impurities (e.g., residual solvents, free amino groups) can sabotage coupling efficiency or lead to failed syntheses. Here’s what to prioritize when selecting a supplier:

1. Purity (≥98%): Non-negotiable for reproducible results.
2. Certifications: ISO, GMP, or FDA compliance ensures quality control.
3. Packaging: Moisture-proof, light-resistant containers prevent degradation.
4. Scalability: Flexibility in quantities (1g to 500g+) saves long-term costs.
5. Support: Technical assistance for solubility, storage, or synthesis issues.

Cutting corners risks wasted time, funding, and credibility. Let’s compare your options.
