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 ...
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.
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 ...
This is a list of chemotherapeutic agents, also known as cytotoxic agents or cytostatic drugs, that are known to be of use in chemotherapy for cancer.This list is organized by type of agent, although the subsections are not necessarily definitive and are subject to revision.
Non-small cell lung cancer, oesophageal cancer, uterine cervical cancer, head and neck cancer and urothelial cancer: Nephrotoxicity, myelosuppression and nausea and vomiting (30-90%). Oxaliplatin: IV: Reacts with DNA, inducing apoptosis, non-cell cycle specific. Colorectal cancer, oesophageal cancer and gastric cancer
This indirect method is often used because aryl halides are relatively weaker electrophiles than alkyl halides and thus poorly alkylate diethyl malonate. [3] Methods using Caesium carbonate and copper(I) iodide have been developed to overcome this difficulty however.
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).
