<p>Stability Hygroscopic<br>Applications 4-Ethylcatechol is one of the main phenolic off-flavour markers in French ciders.<br>References Alonso-Salces, R., et al.: Anal. Bioanal. Chem., 379, 464 (2004), Xu, Y., et al.: J. Agr. Food Chemi., 55, 3051 (2007),<br></p>

<p>Applications Benzyl Acetate, is found naturally in many flowers, It has pleasant sweet aroma reminiscent of jasmine, and thus is used widely in perfumery industry, and also as a flavouring agent. It is also used as a solvent.<br>References Schiestl, F. P., et al.: J. Chem. Ecology, 29 (2004); Qian-qian, M., et al.: Jingxi Huagong, 30, 442 (2013);<br></p>

<p>Stability Hygroscopic<br>Applications L-Glutamic Acid, Magnesium Salt Hydrobromide is an metabolite of L-Glutamic acid, a non-essential amino acid. Its salt form (glutamate) is an important neurotransmitter that plays a key role in long-term potentiation and is important for learning and memory. It is also a key molecule in cellular metabolism. L-Glutamic Acid, Magnesium Salt Hydrobromide has also been investigated for sedative properties as a tranquilizer.<br>References McEntee, W., et al.: Psychopharmacology, 111, 391 (1993), Manev, H., et al.: Mol. Pharmacol., 36, 106 (1989), Hamanaka, T., et al.: Toho. Igakkai. Zasshi., 20, 663 (1973);<br></p>

<p>Applications L-Glutamine-2,3,3,4,4-d5 is the isotope labelled analog of L-Glutamine (G597000); an essential amino acid that is a crucial component of culture media that serves as a major energy source for cells in culture. L-Glutamine is very stable as a dry powder and as a frozen solution. In liquid media or stock solutions, however, L-glutamine degrades relatively rapidly. Optimal cell performance usually requires supplementation of the media with L-glutamine prior to use.<br>References Rivett, A., et al.: J. Biol. Chem., 260, 300 (1985); Watford, M., et al.: Metabolism, 49, 141 (2000); Wilmore, D., et al.: J. Nutr., 131, 2543S (2001)<br></p>

<p>Applications 4-Aminobutyl-d8 Guanidine is the labelled analog of the decarboxylation product of the amino acid arginine (A769500) and also an intermediate in polyamine biosynthesis.<br>References Golding, B.T., et al.: Biochem. Soc. Trans., 22, 391S (1994);<br></p>
