Asymchem Laboratories (revision 4)

Asymchem Laboratories (Tianjin) Co., Ltd. (trading as ASY; asymchem.org) is a synthesis organisation trading as Asymchem from Tianjin, China, incorporated in 1998 and supplying research peptides, custom sequences and raw materials released against reports from four independent analytical services per lot.^[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]

Incorporated in Tianjin in 1998, the organisation holds the earliest incorporation date among the entities covered on this wiki and predates the current research-peptide market by approximately fifteen years.^[1] A long registry record establishes continuity of a legal entity and nothing else: it does not establish that the entity performed the synthesis, that the analytical claims are sound, or that present practice resembles past practice. Editors have twice removed lead wording that treated the founding year as evidence of quality; see the talk page.

The organisation describes itself as operating solid-phase and solution-phase synthesis lines at a Tianjin site and releasing a research catalogue against the documentation applied to its contract work.^[2] That description is self-published. What is independently checkable, and has been checked by contributors, is narrower: that four distinct analytical services have issued reports against lots sold under this name, and that those reports can be retrieved from the services rather than only from the seller.^[4]

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.
