A notable method for synthesizing acetamidomalon ester is described in a 1950 patent, [1] which cites a procedure previously featured in Organic Syntheses. [2] The synthesis procedure involves the preparation of malonic acid diethyl ester in acetic acid combined with sodium nitrite (NaNO 2), resulting in diethyl isonitrosomalonate (also known as α-oximinomalonic acid diethyl ester).
Diethyl malonate, also known as DEM, is the diethyl ester of malonic acid. It occurs naturally in grapes and strawberries as a colourless liquid with an apple-like odour, and is used in perfumes. It is also used to synthesize other compounds such as barbiturates, artificial flavourings, vitamin B 1, and vitamin B 6.
Malonic acid (up to 37.5% w/w) has been used to cross-link corn and potato starches to produce a biodegradable thermoplastic; the process is performed in water using non-toxic catalysts. [ 25 ] [ 26 ] Starch-based polymers comprised 38% of the global biodegradable polymers market in 2014 with food packaging, foam packaging, and compost bags as ...
Amobarbital (5-ethyl-5-isoamylbarbituric acid), like all barbiturates, is synthesized by reacting malonic acid derivatives with urea derivatives. In particular, in order to make amobarbital, α-ethyl-α-isoamylmalonic ester is reacted with urea (in the presence of sodium ethoxide ).
Chaparral (or Larrea tridentata) – a plant used to make a herbal remedy which is sold as cancer treatment. Cancer Research UK state that: "We don't recommend that you take chaparral to treat or prevent any type of cancer."

Diethyl oxomalonate is the diethyl ester of mesoxalic acid (ketomalonic acid), the simplest oxodicarboxylic acid and thus the first member (n = 0) of a homologous series HOOC–CO–(CH 2) n –COOH with the higher homologues oxalacetic acid (n = 1), α-ketoglutaric acid (n = 2) and α-ketoadipic acid (n = 3) (the latter a metabolite of the amino acid lysine).
Methylmalonic acid is elevated in 90–98% of patients with vitamin B 12 deficiency. It has lower specificity since 20–25% of patients over the age of 70 have elevated levels of methylmalonic acid, but 25–33% of them do not have B 12 deficiency. For this reason, the testing of methylmalonic acid levels is not routinely recommended in the ...
Disodium malonate is a sodium salt of malonic acid with the chemical formula CH 2 (COONa) 2. It is a white crystal soluble in water but not in alcohols, esters or benzene. It can be prepared from the reaction of sodium hydroxide and malonic acid: CH 2 (COOH) 2 + 2 NaOH → CH 2 (COONa) 2 + 2 H 2 O
