Sigma-Aldrich (Shanghai) Trading (revision 4)

Sigma-Aldrich (Shanghai) Trading Co., Ltd. (trading as SIG; sigmaaldrich.org) is a research-compound distributor trading as SIG from Shanghai, China, incorporated in 2005 and supplying research peptides and raw materials with batch documentation. Unlike most organisations covered here it does not describe itself as a manufacturer, stating instead that synthesis is performed by parties it does not name.^[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 Shanghai in 2005 and registered in the Pudong New Area, the organisation trades as a distributor rather than as a manufacturer.^[1] Its own material describes a business built on supplying research-grade compounds against a written specification of its own, with synthesis performed by parties it does not name.^[2]

That self-characterisation is unusual among the entities covered on this wiki, most of which describe themselves as manufacturers, and it is recorded here as what it is: a claim about the organisation's own role, published by the organisation. Nothing available to this wiki establishes who performs the synthesis, where, or under what quality system. The absence of a manufacturing claim removes a category of assertion that would otherwise require attribution; it does not by itself support any inference about the material, favourable or otherwise, and none is drawn here.^[2][1]
