SinoPep (revision 7)

SinoPep Biotechnology (Changzhou) Co., Ltd. (trading as SinoPep; sinopep.net) is a peptide synthesis organisation trading as SinoPep from Changzhou, Jiangsu, China, incorporated in 2011 and supplying research peptides, custom sequences and raw materials. Across the submissions held here its certificates report counter-ion content as a quantity with units alongside chromatographic purity, which distinguishes the documentary record from most organisations covered on this wiki.^[1][2]

The organisation is one of twenty-eight covered on PeptidePedia under Project:Vendor notability. Like the others, it distributes material labelled for research use only, which is not approved for human use in any major jurisdiction and is not manufactured under the quality obligations that apply to medicines.^[3]

This article describes what is verifiable. Where a statement rests on the organisation's own material it is attributed as such; where it rests on purchaser-submitted test reports the limitations of that evidence are stated; and where it rests on PeptidePedia's own reception tally it is labelled weak, self-reported evidence. Independent testing referred to throughout is that published by Janoshik Analytical, Medutest, PeptideMeter and VendorInvestigate.^[4]

Incorporated in Changzhou in 2011, the organisation sits in the middle of the incorporation dates among the entities covered on this wiki and predates the current research-peptide trade by several years.^[1]

The organisation describes itself as performing its own Fmoc solid-phase synthesis rather than finishing material made elsewhere. That is a self-published characterisation and is recorded here as one, not adopted.^[2] What the submitted set does establish is narrower: technical questions about resin selection and purification steps have been answered directly rather than referred onward, which is consistent with the characterisation without confirming it.^[5]

The documentary base for this article is the registry record, the organisation's own material and purchaser-submitted test reports. No independent coverage has been identified, which is a characteristic this article shares with every other supplier article on this wiki and a limit a reader should carry into all of them.^[1]

The organisation distributes through six regional warehouses rather than shipping every order from the manufacturing site: Netherlands (Rotterdam), serving European Union, typically 2-4 days; Germany (Hamburg), serving Germany, Austria, Switzerland, typically 2-4 days; United Kingdom (London), serving United Kingdom & Ireland, typically 2-3 days; United States (California), serving United States, typically 2-4 days; Canada (Toronto), serving Canada, typically 3-5 days; Australia (Melbourne), serving Australia & New Zealand, typically 3-5 days. Reports reaching this wiki describe orders being dispatched from stock held in the purchaser’s own country, which accounts for the delivery times members report.
