When working with Fmoc-Lys-OH Hydrochloride (CAS 139262-23-0), purity is non-negotiable. Impurities can compromise your peptide synthesis, lead to failed experiments, and waste valuable time and resources. If you’re a quality-conscious buyer, this guide will show you how to verify the purity of your Fmoc-Lys-OH Hydrochloride and ensure you’re using a certified pure product for your research or industrial applications.
What is Fmoc-Lys-OH Hydrochloride?
Fmoc-Lys-OH Hydrochloride, also known as Nα-Fmoc-L-lysine hydrochloride, is a protected amino acid derivative widely used in peptide synthesis. Its CAS number is 139262-23-0, and it’s essential for introducing lysine residues into peptides while protecting the amino group during synthesis.
Key features of high-purity Fmoc-Lys-OH Hydrochloride include:
- Purity ≥98%
- Low levels of impurities (e.g., free amino acids, residual solvents)
- Compatibility with Fmoc-based solid-phase peptide synthesis (SPPS)
Why Purity Matters in Fmoc-Lys-OH Hydrochloride
Using certified pure Fmoc-Lys-OH Hydrochloride ensures:
- High coupling efficiency: Impurities can reduce reaction yields.
- Reproducibility: Consistent quality leads to reliable results.
- Minimized side reactions: High-purity reagents reduce the risk of unwanted byproducts.
How to Verify the Purity of Fmoc-Lys-OH Hydrochloride
Here’s a step-by-step guide to verifying the quality of your Fmoc-Lys-OH Hydrochloride:
1. Request a Certificate of Analysis (CoA)
A CoA is a document provided by the supplier that details the product’s purity, identity, and quality. Look for:
- Purity percentage (typically ≥98%)
- Impurity levels (e.g., free amino acids, residual solvents)
- Analytical methods used (e.g., HPLC, NMR)
2. Perform In-House Testing
If you have the resources, conduct your own tests to verify purity. Common methods include:
- High-Performance Liquid Chromatography (HPLC): Measures purity and identifies impurities.
- Nuclear Magnetic Resonance (NMR): Confirms the chemical structure.
- Mass Spectrometry (MS): Determines molecular weight and detects contaminants.
3. Check Supplier Reputation
Choose suppliers with a strong reputation for quality and reliability. Look for:
- Customer reviews and testimonials
- Industry certifications (e.g., ISO, GMP)
- Transparency in documentation and testing methods
4. Inspect Packaging and Labeling
High-quality suppliers use proper packaging and labeling to ensure product integrity. Look for:
- Clear labeling with CAS number, batch number, and expiration date
- Sealed containers to prevent contamination
- Storage instructions to maintain stability
