Oxalate (systematic IUPAC name: ethanedioate) is an anion with the chemical formula C 2 O 2− 4. This dianion is colorless. It occurs naturally, including in some foods. It forms a variety of salts, for example sodium oxalate (Na 2 C 2 O 4), and several esters such as dimethyl oxalate ((CH 3) 2 C 2 O 4). It is a conjugate base of oxalic acid.

C 2 O 4−2 is a dicarboxylic acid dianion with chemical name Oxalate. Oxalate is also called Ethanedioate or Oxalate Ion or Oxalic Acid Dianion. It is obtained by deprotonation of both the carboxy groups of C 2 H 2 O 4 (oxalic acid). It is widely used for derivatives, such as salts of oxalic acid, for example, dimethyl oxalate or sodium oxalate.

2021年10月14日 · It is an oxalate and a dicarboxylic acid dianion. It is a conjugate base of an oxalate (1-). Oxalate is a salt or ester of oxalic acid. Derivatives of OXALIC ACID. Included under this heading are a broad variety of acid forms, salts, esters, and amides that are derived from the ethanedioic acid structure. COD records with this CID as component.

Oxalate is a divalent organic anion that affects many biological and commercial processes. It is derived from plant sources, such as spinach, rhubarb, tea, cacao, nuts, and beans, and therefore is commonly found in raw or processed food products.

2024年5月16日 · We argue that oxalate and its metabolism are important above and beyond kidney stone formation. There is emerging evidence that increased concentrations of oxalate could be a driver of chronic kidney disease progression. Furthermore, oxalate has been implicated in cardiovascular disease.

Introducing the Oxalate Anion. Complicated names aside, the oxalate anion is remarkably simple. It consists of two carbon atoms and four oxygens, giving it a negative charge, which means it’s eager to bind with positively charged ions, like calcium, in your body. Formation within the Body. So, how do these compounds appear inside you?

This section is deprecated (see here for details), but these live search links provide equivalent functionality to the table that was previously shown here. CID 971 (Oxalic Acid)

1990年10月1日 · While the oxalate ion is planar in some crystalline oxalates, it is twisted in others, with variable twist angles between the carboxylate groups. Calculations by AM1 and ab initio procedures have now shown free oxalate ion to have an orthogonal D2h structure.

Oxalate ions, or more commonly known as Ethanedioate or Oxalate Ion, or sometimes even called as the Dianion of Oxalic Acid, is the core component that can be found inside the structure of oxalate. Interestingly, these ions are obtained from deprotonation from the C₂O₄ structure.

2016年4月18日 · Students measure the IR and Raman spectra of solid Na 2 C 2 O 4, K 2 C 2 O 4, and Cs 2 C 2 O 4, and a nearly saturated aqueous solution of K 2 C 2 O 4. They also carry out Gaussian calculations on the oxalate anion to predict the vibrational wavenumbers of both the planar and nonplanar structures and use the results to assign the spectra.
