The odor detection threshold is the lowest concentration of a certain odor compound that is perceivable by the human sense of smell. The threshold of a chemical compound is determined in part by its shape, polarity, partial charges, and molecular mass. The olfactory mechanisms responsible for a compound's different detection threshold is not ...
Triethylamine is the chemical compound with the formula N(CH 2 CH 3) 3, commonly abbreviated Et 3 N. Like triethanolamine and tetraethylammonium , it is often abbreviated TEA. [ 8 ] [ 9 ] It is a colourless volatile liquid with a strong fishy odor reminiscent of ammonia .
Odour activity value (OAV) is a measure of importance of a specific compound to the odour of a sample (e.g. food). It is calculated as the ratio between the concentration of individual substance in a sample and the threshold concentration of this substance (odour threshold value, the minimal concentration that can be detected by human nose).
DIPEA is a sterically hindered organic base that is commonly employed as a proton scavenger. Thus, like 2,2,6,6-tetramethylpiperidine and triethylamine, DIPEA is a good base but a poor nucleophile, DIPEA has low solubility in water, which makes it very easily recovered in commercial processes, a combination of properties that makes it a useful organic reagent.
Triethylenetetramine (TETA and trien), also known as trientine when used medically, is an organic compound with the formula [CH 2 NHCH 2 CH 2 NH 2] 2. The pure free base is a colorless oily liquid, but, like many amines, older samples assume a yellowish color due to impurities resulting from air oxidation. It is soluble in polar solvents.

4-Toluenesulfonyl chloride (p-toluenesulfonyl chloride, toluene-p-sulfonyl chloride) is an organic compound with the formula CH 3 C 6 H 4 SO 2 Cl. This white, malodorous solid is a reagent widely used in organic synthesis. [2] Abbreviated TsCl or TosCl, it is a derivative of toluene and contains a sulfonyl chloride (−SO 2 Cl) functional group.
Trolamine salicylate (Aspercreme, Aspergel) is an organic compound with the chemical formula [HN(CH 2 CH 2 OH) 3] + C 6 H 4 (OH)(COO −).It is a salt of triethanolamine and salicylic acid, i.e. the compound consists of protonated triethanolamine and the conjugate base of salicylic acid, salicate.
