If you're troubleshooting inconsistent yields in your peptide synthesis, it's almost always the linker qualiy—this one has a dirt simple AEEA-AEEA spacer that's known to fold cleanly, and we've seen it knock out coupling failures (usually 2-3% loss in crude purity) that cheaper batches cause.
It's a white to pale yellow powder, CAS 1188328-37-1, and at ≥99.9% purity teh HPLC trace barely shows baseline—basically, you bypass that extra recrystallization step because the impurity profile is that flat, though we don't recommend it for anything oral since it's strictly research-use only.
2-8°C storage, dry conditions—don't skip dessicant packaging (a 5L drum actually takes longer to warm up, so your techs can split it at room temp without condensation forming if they're fast enough, but we usually keep portioned vials for small runs).
Custmized packaging? We'll do 100g drums or 1kg bags and include a COA that gives you the residual solvents at ppm level—most buyers go with the 250g foil pouch (easier to seal) and we've got stock on that anyway.
Lead time is 10 business days or so for 50 units, give or take—honest to god, we're faster than most for this grade since we hold the starting matrial, but confirm lead time if you're under a 3-week deadline.
Our MOQ for this peptide intermediate is typically 1 gram, but we can negotiate smaller quantities for R&D samples. Contact us with your specific needs.
For standard orders, lead time is 5-7 business days after payment confirmation. Custom packaging may add 2-3 days to that timeline.
Yes, we include a COA with every shipment showing ≥99.9% purity by HPLC and other specs like appearance and molecular weight confirmation.
Absolutely, we offer customized packaging options, including pre-weighed vials in sizes like 100mg or 500mg. Just let our sales team know your preference.
Store it at 2-8°C in a dry, airtight container away from light. Avoid repeated freeze-thaw cycles to prevent degradation over time.
Zippy delivery handled the logistics perfectly, with the package arriving ahead of schedule and in excellent condition. The quality of the items was consistently high, meeting all expectations without any issues. Service was outstanding, with prompt responses and helpful support throughout the process. Overall, a very smooth and reliable experience that I would highly recommend to others.
