Where can I find a reliable Fmoc-Gly-OH supplier in China?
Baishixing offers Fmoc-Gly-OH with purity ≥99% by HPLC and full COA. Supply capacities range from tens of grams to hundreds of kilograms. Contact their technical support for specific packaging and lead times.
What is the CAS number for Fmoc-Gly-OH?
The CAS number is 29022-11-3. This registry number is used for ordering, customs declaration, and database searches relating to Fmoc-glycine.
Can Fmoc-Gly-OH be used for solid-phase peptide synthesis?
Yes. It is a standard Fmoc-protected amino acid designed for SPPS. The carboxyl group reacts with resin-bound amines, and the Fmoc group is removed under piperidine conditions. Conduct a Kaiser test to verify coupling efficiency.
How should Fmoc-Gly-OH be stored?
Store it in a tightly sealed container, away from sunlight and moisture. For long-term stability, keep the material at 2–8 °C. Under these conditions, it remains stable for at least 36 months.
What purity levels are available?
Standard purity is ≥99.0% as determined by HPLC. Each lot is also checked for water content and residual solvents. Custom purity profiles or additional impurity analysis can be arranged upon request.
Does Fmoc-Gly-OH require cold-chain transport?
In sealed packages, normal shipping is acceptable if the temperature stays below 30 °C for a few days. For larger quantities or warm climates, insulated packaging with cooling elements can be provided.
What is the molecular weight of Fmoc-Gly-OH?
The molecular weight is 297.31 g/mol, calculated from the formula C₁₇H₁₅NO₄. Use this value for molar equivalent calculations when preparing resin loading or coupling stoichiometry.
Is a certificate of analysis provided with each shipment?
Yes, every batch ships with a COA that lists the HPLC purity, water content, loss on drying, appearance, and residual solvent values. The COA also includes the batch number and production date.
Unlike many distributors who repackage generic Fmoc-Gly-OH without deep process control, Baishixing directly coordinates manufacturing with documented quality control and flexible batch sizing. The combination of strict ICH-residual solvent compliance, complete COA reporting, and stable scaling keeps consistent purity from kilogram to tonnage orders. This makes Baishixing’s Fmoc-Gly-OH a practical choice for both academic researchers and pharmaceutical companies that require supply security and regulatory documentation without compromising on raw material transparency.
