Odor threshold value (OTV) (also aroma threshold value (ATV), Flavor threshold) is defined as the most minimal concentration of a substance that can be detected by a human nose. Some substances can be detected when their concentration is only few milligrams per 1000 tonnes, which is less than a drop in an Olympic swimming pool. Odor threshold ...
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).
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.
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.
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.
According to the report, 77 percent of plant-based protein powders, 79 percent of organic protein powders, and 65 percent of chocolate-flavored protein powders tested over the California ...
Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.
