What is the CAS number of Fmoc-Gly-OH?
The CAS number is 29022-11-5. This identifies the chemical as N-[(9H-fluoren-9-ylmethoxy)carbonyl]glycine, commonly known as Fmoc-glycine or Fmoc-Gly-OH.
Can I get a Certificate of Analysis (COA) for each lot?
Yes. A COA is issued for every batch and includes HPLC purity, loss on drying, residual solvent analysis, and appearance test results. The COA is provided directly with shipment or upon request via the Baishixing document portal.
What is the minimum order quantity (MOQ) for wholesale?
Standard MOQ is 25 kg, which corresponds to one drum. For first-time calibration or process validation, smaller trial quantities can be supplied, but pricing is then based on non-bulk scale.
Is Fmoc-Gly-OH available in GMP grade?
Baishixing offers production lots that are tested according to pharmacopeia-style methods, but the material is typically classified as a highly pure industrial reagent. Please contact our technical team to confirm whether your specific submission requirements can be met.
How should Fmoc-Gly-OH be stored?
Keep the product sealed in its original aluminum foil bag, store in a cool, dry area below 25 °C, and avoid long-term exposure to light. Under these conditions, the material remains stable for at least 24 months from manufacturing date.
What is the typical lead time for bulk delivery?
For the 25 kg standard packaging, lead time is 5–7 working days after order confirmation, depending on stock availability. Custom packaging or large-volume orders (above 200 kg) may require a separate production slot.
Do you provide custom packaging or special batch requirements?
We provide packaging ranging from 1 kg to 25 kg and can arrange inert-gas sealing if required. Special requirements such as lower particle size or specific container types can be evaluated based on order volume.
Fmoc-Gly-OH supplied by Baishixing focuses on manufacturability rather than over-promising specification sheets. Compared to general reagent suppliers, our bulk material is consistently tested for residual solvents and heavy metals, not only for endpoint purity. That attention to lot documentation makes it suitable for CMOs and peptide producers that cannot afford variation in their raw-material baseline. For R&D groups transitioning toward production, having the same grade in both small custom vials and 25 kg drums simplifies scale-up. If your peptide synthesis workflow depends on reproducible coupling efficiency, regulatory-minded documentation, and predictable supply schedules, this Fmoc-Gly-OH grade is a practical fit.
