Formamide
Formamide, also known as methanamide or ameisensaeureamid, belongs to the class of organic compounds known as carboximidic acids. These are organic acids with the general formula RC(=N)-OH (R=H, organic group). Formamide, in its pure state, has been used as an alternative solvent for the electrostatic self-assembly of polymer nanofilms. Formamide exists in all living organisms, ranging from bacteria to humans. Formamide has been detected, but not quantified in several different foods, such as hyssops, rose hips, asian pears, brassicas, and green bell peppers. It has been used as a softener for paper and fiber. Inhalation of large amounts of formamide vapor may require medical attention. In the past, formamide was produced by treating formic acid with ammonia, which produces ammonium formate, which in turn yields formamide upon heating:HCOOH + NH3 → HCOO−NH+4HCOO−NH+4 → HCONH2 + H2O. Formamide is also generated by aminolysis of ethyl formate: HCOOCH2CH3 + NH3 → HCONH2 + CH3CH2OH. The current industrial process for the manufacture of formamide involves either the carbonylation of ammonia: CO + NH3 → HCONH2. An alternative two-stage process involves the ammonolysis of methyl formate, which is formed from carbon monoxide and methanol: CO + CH3OH → HCOOCH3HCO2CH3 + NH3 → HCONH2 + CH3OH. Formamide is used in the industrial production of hydrogen cyanide. Formamide has been shown to exhibit hematoxicity in animals and is considered hazardous by prolonged exposure through inhalation, oral intake and dermal absorption. Formamide is a metabolite used for biological monitoring of workers exposed to N-N-dimethylformamide (DMF).(PMID 7622279).
Scandium
Scandium, also known as 21sc or escandio, is a member of the class of compounds known as homogeneous transition metal compounds. Homogeneous transition metal compounds are inorganic compounds containing only metal atoms,with the largest atom being a transition metal atom. Scandium can be found in a number of food items such as butternut, common hazelnut, coconut, and cashew nut, which makes scandium a potential biomarker for the consumption of these food products. Scandium is present in most of the deposits of rare-earth and uranium compounds, but it is extracted from these ores in only a few mines worldwide. Because of the low availability and the difficulties in the preparation of metallic scandium, which was first done in 1937, applications for scandium were not developed until the 1970s. The positive effects of scandium on aluminium alloys were discovered in the 1970s, and its use in such alloys remains its only major application. The global trade of scandium oxide is about 10 tonnes per year .
formate
Formate, also known as formic acid or methanoic acid, is a member of the class of compounds known as carboxylic acids. Carboxylic acids are compounds containing a carboxylic acid group with the formula -C(=O)OH. Formate is soluble (in water) and a weakly acidic compound (based on its pKa). Formate can be found in a number of food items such as mammee apple, chicory roots, malabar spinach, and grapefruit, which makes formate a potential biomarker for the consumption of these food products. Formate (IUPAC name: methanoate) is the anion derived from formic acid. Its formula is represented in various equivalent ways: CHOO‚àí or HCOO‚àí or HCO2‚àí. It is the product of deprotonation of formic acid. It is the simplest carboxylate anion. A formate (compound) is a salt or ester of formic acid .
