Toxicology

Applications 3-Bromopropionic-2,2,3,3-d4 Acid is the labeled analog of 3-Bromopropionic acid (B687705). 3-Bromopropionic Acid is used as a reagent in the synthesis of nitrogen containing diselenides which exhibit antioxidant activity. Also used as a reagent in the synthesis of indolin-2-one-based multi-targeted receptor tyrosine kinase inhibitors as potential anticancer agents. References Nascimento, V., et al.: Eur. J. Med. Chem., 87, 131 (2014); Zhang, L., et al.: Eur. J. Med. Chem., 82, 139 (2014)

Applications 2-Chlorophenylboronic Acid used in the preparation of imidazo[1,2-a]pyridine amides which has tuberculostatic activity. References Kang, S., et al.: J. Med. Chem., 57, 5293 (2014);

Applications N-Acetylpiperazine-d4 is labelled N-Acetylpiperazine-d4 which was used to prepare (aryl)sulfanyltriazoles with HIV-1 non-nucleoside reverse transcriptase inhibiting activities. It was also used to synthesize diphenylpyrazolecarboxamides as heat shock protein chaperone inhibitors and anticancer agents. References Wang, Z., et al.: Bioorg. Med. Chem. Lett., 16, 4174 (2006); Brough, P., et al.: J. Med. Chem, 51, 196 (2008)

Impurity Miconazole EP Impurity D Applications Isoconazole Nitrate acts as an antibacterial in the local treatment of vaginitis; antifungal agent (1,2). References 1. Asikoglu, M. et al.: J. Pharm.

Applications Crotonoyl chloride is an unsaturated acid chloride that is used as an acylation agent in synthetic chemistry. Crotonoyl chloride is also used as a reagent in the synthesis of (-)-Exiguolide, a 16-membered macrolide that is used as a fertilization inhibitor. Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package References Arumugam, V., et al.: Tetrahedron Lett., 38, 6473 (1997); Han, X., et al.: Eur. J. Org. Chem., 2013 (1193 (2013); Rathke, M. & Sullivan, D.: Tetrahedron Lett., 14, 1297 (1973)

Applications (4-(3-Methylbutan-2-yl)phenyl)methanol is an intermediate used in the synthesis of 1-Desmethyl-2-methylpropyl Amorolfine (D292315), which is an analogue of Amorolfine Hydrochloride (A634170). Amorolfine hydrochloride is a salt of Amorolfine which is a morpholine antifungal drug. It is a topical solution for the treatment of toenail infections.
