menionate

Menionate is a non-specific term encountered in chemical literature that may refer to any compound in which a carboxylate moiety derived from a hypothetical menonate acid forms a salt or ester. There is no single compound universally known by this name; instead, menionate is used variably across sources and is typically qualified by the counterion or the ester group to identify a substance.

In most cases, menionate denotes a class rather than a single structure. It can refer to metal salts such as sodium menonate or potassium menonate, or to organic esters in which the carboxyl group of the parent acid is substituted with an alkyl or aryl group. The exact geometry, reactivity, and applications depend on the identity of the cation and the ester substituent.

Because the term is not standardized, reporting of a menionate compound should include its full chemical name and/or a molecular formula, and ideally the CAS number. In scholarly work, menionate is often a placeholder prior to full characterization; it can also appear from typographical errors or confusion with related carboxylates and oxoanions.
