Analytical Reagents

Sodium diethyldithiocarbamate trihydrate was used during the synthesis of N-allylpeptides, in a study outlining the strategy to synthesize and purify a hydrogen bond surrogate (HBS) α-helix in ∼1 week.
Spin trap used in conjunction with Fe2+ to detect NO in brain, kidney, liver, and other tissues. Simultaneous direct measurement of NO* and pO2 has been reported. A copper chelator, it has been used to quantitate copper in biological materials by ESR and is an inhibitor of superoxide dismutase, ascorbate oxidase, and other enzymes.

Sodium tetraphenylborate (NaTPB) may be used as an anion discriminator in the poly(vinyl chloride) (PVC) based membrane potentiometric sensor for the determination of copper in aqueous solutions. Its addition to membranes has been proven to be beneficial towards optimizing sensing selectivity and decreasing bulk membrane impedance which result in substantial improvement of Cu2+ -selective potentiometric sensor performance. NaTBP has also been investigated as a lipophilic additive in terbium(III) membrane electrode for its potential response towards terbium(III) ions. It may be used as an aqueous derivatization reagent for organomercury prior to its determination in environmental samples by gas chromatography (GC) combined with atomic fluorescence spectrometry (AFS), microwave-induced plasma atomic emission spectrometry (AES), and mass spectrometry (MS).

Sodium tetrapropylborate (NaBPr4) belongs to the class of tetraalkylborates, which are commonly used as derivatization agents to accomplish the multielement speciation of organometallic compounds on account of their ability to react with elements such as mercury, lead and tin. NaBPr4 is preferred because it eliminates the need for organic solvents as required in Grignard reactions, also resulting in reduced analysis time.
