Products] Ion Pair Reagents for HPLC
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
unique chromatography products, "TCI Chiral" of
TCI original chiral separation columns, "TCI
Dual" of ODS + Ion-Exchange Mixed-Mode columns and
"TCI Pack and Kaseisorb" of high performance
ODS columns are listed.
TCIMAIL contains technical papers
contributed by leading professors and scientists. We also
introduce our new reagents in the fields of synthetic
organic chemistry, materials chemistry, bioscience and
analytical science. Examples of application and use are
explained in an easy way, using various schemes and
Stable Isothiocyanating Reagent with Ease of Handling
(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.
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.
