What is the CAS number for Fmoc-Gly-OH?
The CAS number for Fmoc-Gly-OH is 29022-11-3. It has a molecular formula of C17H15NO4 and a molecular weight of 297.31 g/mol. This information is commonly used for regulatory filings, ordering, and verifying product identity in chemical databases.
How is the purity of Fmoc-Gly-OH determined?
Purity is determined using high-performance liquid chromatography at 220 nm. Each batch is analyzed for area purity and main peak content. Only batches with ≥99% purity are released for shipment, and the full results are included in the Certificate of Analysis. Additional quality checks such as residual solvent and water content are also performed.
Can I get a Certificate of Analysis for each batch?
Yes, every order includes a Certificate of Analysis (COA) specific to the batch number. The COA reports assay, related substances, residual solvents, heavy metals, and endotoxin levels. Additional documents, such as handling instructions and stability data, can be provided upon request. This ensures full traceability from raw material to delivery.
What packaging options are available for large orders?
Standard packaging for large orders includes 1 kg aluminum-lined bags and 25 kg fiber drums. For smaller quantities, 100 g and 500 g bottles are available. Custom packing sizes can be accommodated after quotation, with minimum order quantities applied. Please contact our sales team for specific container and labeling requirements.
What are the recommended storage conditions?
Store Fmoc-Gly-OH in a tightly sealed original container, in a cool dry place below 25 °C, and protected from light and moisture. Under these conditions, the product remains stable for at least 24 months. Avoid exposure to heat or direct sunlight to prevent degradation. For long-term storage, keep the container away from acidic or basic fumes.
Is this product suitable for GMP peptide manufacturing?
The standard grade is designed for research and non-GMP manufacturing. For GMP peptide production, we offer a dedicated GMP-grade version with qualified manufacturing processes, stricter impurity profiling, and more complete documentation. Please contact us with your quality requirements before ordering so we can validate the raw material and process controls.
What is the lead time for factory-direct orders?
For stock items, dispatches are made within 3 working days after order and payment confirmation. For tonnage or custom-specification orders, production typically takes 2 to 3 weeks. Shipping time depends on destination, and we usually provide a tracking number after dispatch. We also offer urgent handling for small quantities if requested in advance.
How does your quality control compare to resellers?
Because we produce and test in the same facility, every batch is subjected to immediate quality control after synthesis, eliminating transport-related degradation and documentation losses. Unlike resellers, we can directly adjust purity thresholds, reduce variability, and provide faster response times for contract requests. This internal control model helps maintain a lower total cost in scaled-up projects.
Compared with resold or imported Fmoc-Gly-OH, the factory-direct product from Baishixing offers verified purity (≥99%), low endotoxin, and complete batch traceability, while keeping total cost lower for recurring users. Although many suppliers list similar specifications, in-house production ensures consistent quality across large-volume orders, faster lead times, and direct specification adjustments. This product is well suited for research groups and manufacturing teams that value supply security and process reproducibility over the cheapest initial price.
