Queteletin

Queteletin is a term that appears in some non-scholarly sources as the name of a chemical compound. There is no entry for Queteletin in major chemical databases, and no peer‑reviewed publication confirms its existence, structure, synthesis, or properties. Because of this lack of verifiable information, Queteletin is not recognized as a distinct chemical entity and cannot be assigned a molecular formula, CAS number, or known biological activity.

The origin of the term is unclear. It may be a misspelling or variant of quercetin, a common flavonol found in many fruits and vegetables, or it may be a fictional or proposed name used in non-scientific contexts. Some attributions link the term to the surname Quetelet, most famously associated with the Quetelet index (body mass index). In the absence of reliable sources, the relationship between Queteletin and those terms remains speculative.

Potential usage: In scholarly writing, it is advisable to avoid using Queteletin unless a primary source provides a verified definition and data. If encountered, readers should check the spelling, context, and source, and prefer established terms such as quercetin when referring to known flavonoids. This article notes the lack of verifiable information and indicates that reliable sources are required to establish a formal identity for Queteletin.
