 [Recommended Products] Ion Pair Reagents for HPLC

 

 

Ion-exchange chromatography systems have previously been utilized in HPLC analysis of ionic samples. Reversed phase partition chromatography using ion-pair reagents has been developed and utilized. The ionic samples form an ion-pair with ion-pair reagents in the mobile phase to become electrically neutral. The increase in hydrophobic character of the ion-pair results in a greater affinity for the reverse stationary phase and leads to sample resolution.

[Product Highlights]
Stable Isothiocyanating Reagent with Ease of Handling

1,1'-Thiocarbonyldi-2(1H)-pyridone (1) is widely used in organosynthetic reactions for the transformation of a primary amino group into an isothiocyanate group.1,2) Both aliphatic and aromatic primary amines can be treated with 1 , to produce the corresponding isothiocyanates in high yields. The reaction proceeds under neutral condition and formed byproduct can be removed by aqueous treatment only, allowing for easy workup and purification. Typically, thiophosgene is used to convert an amino group to isothiocyanate, but requires careful handling due to high toxicity and propensity to hydrolyze. In comparison, 1 is an easy-to-handle isothiocyanating reagent with low toxicity and high stability from moisture.

[Product Highlights]
Potassium Xanthates: Powerful Palladium Scavengers

Potassium xanthate derivatives have been employed as metal scavengers because of their chelating ability of two sulfur atoms. Maloney et al. have reported a comparison of the metal scavenging ability between generally used scavengers like thioureas and dithiocarbamates, and xanthate salts type scavengers like potassium isopropylxanthate and potassium ethylxanthate. As a result of the evaluation, by using an antibiotic containing residual palladium as a model, it has been shown that potassium xanthates can effectively reduce residual palladium under 1 ppm. Furthermore, it is revealed that iodine-doped potassium xanthates are more effective removing the residual palladium.
