Selecting the right supplier for Fmoc-Phe-OH (CAS 35661-40-6) is critical for ensuring successful peptide synthesis, cost efficiency, and project timelines. With countless vendors claiming to offer “high-purity” products, it’s easy to fall into traps like hidden fees, inconsistent quality, or delayed shipments. To simplify your decision, we’ve curated the top 5 suppliers of Fmoc-Phe-OH in 2025, evaluating them on purity guarantees, pricing transparency, and customer support. Plus, learn why KiloBio stands out as a leader in value and reliability.
Why Your Fmoc-Phe-OH Supplier Choice Matters
Fmoc-Phe-OH (N-Fmoc-L-phenylalanine) is a foundational building block for synthesizing peptides used in drug discovery, diagnostics, and academic research. A subpar supplier can lead to:
- Failed Syntheses: Impurities >2% disrupt coupling reactions.
- Budget Overruns: Repurchasing reagents or repeating experiments.
- Project Delays: Slow shipping or inconsistent stock availability.
To avoid these issues, prioritize suppliers who combine rigorous quality control with competitive pricing. Here’s how we evaluated the top contenders.
Evaluation Criteria for Fmoc-Phe-OH Suppliers
We ranked suppliers based on the following factors:
