Collection: Application Specific Reagents

Application Specific Reagents — includes analytical chemistry reagents designed for specific functions, including amino acid sequencing reagents, extraction-spectrophotometry reagents, ion-pairing reagents, and thiol group analysis reagents. Each subgroup has a characteristic reaction mechanism tailored to a specific analytical target.

Application specific reagents are used by analysts and biochemistry researchers for amino acid labeling in protein sequencing by the Edman method, determining SH group content using reagents such as Ellman's reagent, extraction-spectrophotometry of anionic surfactants, and ion-pair formation in chromatographic analysis. These reagents provide high selectivity for specific analytes in complex matrices.

Product examples in this collection: TCI Q0034 110-86-1 Pyridine [Sequencing Solvent], TCI C0142 109-69-3 1-Chlorobutane, TCI T3981 Thiol Quantification Kit, TCI C0646 135-20-6 Cupferron, TCI A5513 103-72-0 Phenyl Isothiocyanate [for HPLC Labeling], TCI D0944 69-78-3 5,5'-Dithiobis(2-nitrobenzoic Acid) [for Determination of SH groups], TCI A5400 74920-80-2 MDEPAP [=1-Methyl-4-(4-diethylaminophenylazo)pyridinium Iodide] [Extraction-spectrophotometric reagent for anionic surfactants], TCI P0364 5624-13-5 Phenylthiohydantoin-aspartic Acid.

Pay attention to the suitability of the reagent with the analytical method used (spectrophotometry, HPLC, sequencing), the analytical purity grade, and the stability of working solutions against light and air. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
