Two amino acids, asparagine and glutamine, have a carboxamide group in them. The properties and reactivity of the carboxamide group arise from the hydrogen bonding capabilities of the -NH₂ group as well as the carbonyl oxygen. Furthermore, the carbon atom in a carboxamide has a low-lying LUMO that is capable of accepting electron density from the nonbonding lone pair on the nitrogen, weakening the carbon-oxygen bond.

Chlorogenic acid (CGA) is the ester of caffeic acid and ()-quinic acid, functioning as an intermediate in lignin biosynthesis.^[1] The term "chlorogenic acids" refers to a related polyphenol family of esters, including hydroxycinnamic acids (caffeic acid, ferulic acid and p-coumaric acid) with quinic acid.^[2]

Despite the "chloro" of the name, chlorogenic acids contain no chlorine. Instead, the name comes from the Greek (light green) and - (a suffix meaning "giving rise to"), pertaining to the green color produced when chlorogenic acids are oxidized.

The cationic detergent benzethonium chloride is a well characterized skin irritant and rare sensitizer.
INFROMATION OF BENZENTHONIUM CHLORIDEBenzethonium chloride, also known as hyamine is a synthetic quaternary ammonium salt. This compound is an odorless white solid, soluble in water. It has surfactant, antiseptic, and anti-infective properties, and it is used as a topical antimicrobial agent in first aid antiseptics. It is also found in cosmetics and toiletries such as mouthwashes, anti-itch ointments, and antibacterial moist towelettes. Benzethonium chloride is also used in the food industry as a hard surface disinfectant.
USESn addition to its highly effective antimicrobial activity, benzethonium chloride contains a positively charged nitrogen atom covalently bonded to four carbon atoms. This positive charge attracts it to the skin and hair. This contributes to a soft, powdery afterfeel on the skin and hair, as well as long-lasting persistent activity against microorganisms. Also, this positively charged hydrophilic part of the molecule makes it a cationic detergent.

Benzethonium chloride is also used to titrate the quantity of sodium dodecyl sulfate in a mixture of sodium dodecyl sulfate, sodium chloride and sodium sulfate, using dimidium bromide-sulphan blue as an indicator

One typical reaction example is the oxidation of (S)-(−)-2-methyl-1-butanol to (S)-(+)-2-methylbutanal.^[6] 4-Methoxyphenethyl alcohol is oxidized to the corresponding carboxylic acid in a system of catalytic TEMPO and sodium hypochlorite and a stoichiometric amount of sodium chlorite.^[7] TEMPO oxidations also exhibit chemoselectivity, being inert towards secondary alcohols, but the reagent will convert aldehydes to carboxylic acids.

In cases where secondary oxidizing agents cause side reactions, it is possible to stoichiometrically convert TEMPO to the oxoammonium salt in a separate step. For example, in the oxidation of to geranial, 4-acetamido-TEMPO is first oxidized to the oxoammonium tetrafluoroborate.^[8]

TEMPO can also be employed in nitroxide mediated radical polymerization (NMP), a controlled free radical polymerization technique that allows better control over the final molecular weight distribution. The TEMPO free radical can be added to the end of a growing polymer chain, creating a "dormant" chain that stops polymerizing. However, the linkage between the polymer chain and TEMPO is weak, and can be broken upon heating, which then allows the polymerization to continue. Thus, the chemist can control the extent of polymerization and also synthesize narrowly distributed polymer chains.

Calcium iodate can also be used as an iodine supplement in chicken feed.^[1]

Pure copper(I) iodide is white, but samples are often tan or even, when found in nature as rare mineral marshite, reddish brown, but such color is due to the presence of impurities. It is common for samples of iodide-containing compounds to become discolored due to the facile aerobic oxidation of the iodide anion to molecular iodine


USES OF Copper iodide:

• CuI is used as a reagent in organic synthesis. In combination with 1,2- or 1,3 diamine ligands, CuI catalyzes the conversion of aryl, heteroaryl, and vinyl bromides into the corresponding iodides. NaI is the typical iodide source and dioxane is a typical solvent (see aromatic Finkelstein reaction).^[9] Aryl halides are used to form carbon-carbon and carbon-heteroatom bonds in process such as the Heck, Stille, Suzuki, Sonogashira and Ullmann type coupling reactions. Aryl iodides, however, are more reactive than the corresponding aryl bromides or aryl chlorides. 2-Bromo-1-octen-3-ol and 1-nonyne are coupled when combined with dichlorobis (triphenylphosphine)palladium(II), CuI, and diethylamine to form 7-methylene-8-hexadecyn-6-ol.^[10]
• CuI is used in cloud seeding,^[11] altering the amount or type of precipitation of a cloud, or their structure by dispersing substances into the atmosphere which increase water''s ability to form droplets or crystals. CuI provides a sphere for moisture in the cloud to condense around, causing precipitation to increase and cloud density to decrease.
• The structural properties of CuI allow CuI to stabilize heat in nylon in commercial and residential carpet industries, automotive engine accessories, and other markets where durability and weight are a factor.
• CuI is used as a source of dietary iodine in table salt and animal feed.^[11]
• CuI is used in the detection of mercury. Upon contact with mercury vapors, the originally white compound changes color to form copper tetraiodomercurate, which has a brown color.
