Chromatography Standards
3-Methoxytyramine hydrochloride, ≥96.0% (HPLC), MilliporeSigma™ Supelco™
3-Methoxytyramine hydrochloride is a minor dopamine metabolite, found naturally in the cactus, Trichocereus pachanoi.
1-Butanol, Analytical Standard, ≥99.9% (GC), MilliporeSigma™ Supelco™
Butanol, alcohol with higher energy density, lower vapour pressure and low hygroscopicity. 1-Butanol is a potential fuel substitute to gasoline. It is also a feedstock used to produce chemicals. It is produced via two pathways, the synthetic 2-ketoacid pathway and CoA-dependent pathway. It can also be produced by fermentation of biomass-derived carbohydrates.
PESTANAL™ Rafoxanide, MilliporeSigma™ Supelco™
Rafoxanide is a halogenated salicylanilide and an anthelmintic agent. It is widely used against fasciolosis and haemonchosis in sheep and cattle. It also finds applications as an adulticide for Fasciola hepatica and Fasciola gigantica.
