Fipronil and Fipronil Metabolites

We are introducing the labelled Fipronil and three of its metabolites. Fipronil is an insecticide with both crop and animal health applications. It is highly toxic to mammals, birds and bees and may bio-accumulate. It is considered a neurotoxicant and both an eye and skin irritant. It can be very persistent in soil. Fipronil is not approved for usage in the EU.  Item no. 20035Fipronil-(pyrazol-13C3, cyano 13C) 54 CAS-No. 2140327-54-2Item no. 20232Fipronil sulfone-(pyrazol-13C3, cyano-13C)...

Prosulfuron

We are pleased to introduce the newly synthesized deuterated Prosulfuron and two of its metabolites. Prosulfuron is highly soluble, volatile, has a high potential for leaching into groundwater, and can be very persistent in aquatic systems. Prosulfuron and its two metabolites are ecotoxic and show adverse effects on living organisms including mammals. A recent regulation by the EU commission concluded that it was appropriate to remove a former restriction, by which the use of Prosulfuron as an...

Octamethylcyclotetrasiloxane-d12 (D4)

We are pleased to introduce the recently synthesized deuterated Octamethylcyclotetrasiloxane (D4), one of the most abundant siloxanes in the environment. This substance is used by consumers in cosmetics and personal care products, washing and cleaning products, polishes and waxes. It is also used in scientific research and development, and its industrial use includes textile treatment products and dyes. The release of D4 to the environment is likely to occur from cleaning and personal care...

Quinmerac Metabolites

A complete assessment of residue values of all quinmerac metabolites has not been possible up until now due to the lack of availability of the two quinmerac metabolites BH 518-1 and BH 518-4. Today we are pleased to announce that we have added these two metabolites to our product portfolio. In the last review of quinmerac residue levels by the European Food Safety Authority (EFSA), further evaluation of quinmerac metabolite levels was recommended.

6PPD-quinone (labelled and unlabelled)

We are introducing our newly synthesized native and labelled 6PPD-quinone, a highly toxic quinone transformation product of N-(1,3-dimethylbutyl)-N’-phenyl-p-phenylenediamine (6PPD), a worldwide commonly used tire rubber antioxidant. A recent study showed that this tire rubber-derived transformation product could occur at toxic concentrations in urban creeks with proximity to busy roadways in the pacific northwest of the US, where it might be responsible for the high mortality of an aquatic...

Alternaria toxin sulfate derivatives

Alternariol 3-Sulfate Ammonium Salt and Alternariol 9-Methyl Ether 3-Sulfate Ammonium Salt are the ammonium salts of a sulfate derivative of Alternariol and Alternariol 9-Methyl Ether, respectively, which are Alternaria mycotoxins and genotoxins, found in common edible crops. We have recently successfully synthesized these two mycotoxins for your analytical needs. More than 70 different mycotoxins have already been described in literature. The best-known of which are Alternariol (AOH),...
