Collection: Titration Reagents

Titration Reagents — compiles color indicators and auxiliary titration reagents such as metal indicators for calcium and magnesium, fluorometric dyes, and reactive esters, used to mark the endpoint of titration reactions both visually and instrumentally.

These titration indicators and reagents are used by laboratory analysts to determine the equivalence point in acid-base titrations, complexometric titrations, or the determination of metal content such as calcium and magnesium through color change or fluorescence signal. Indicators such as calmagite and calcein are commonly used for mineral content determination, while other reagents are used for redox titrations and water content determination.

Example products in this collection: TCI X0052 29412-85-9 Methylxylenol Blue, TCI C0003 Calcein Sodium Salt (mixture of isomers) [for Fluorometric Determination of Ca], TCI X0016 125-31-5 p-Xylenol Blue, TCI C0004 154071-48-4 Calcein (mixture of isomers) [for Fluorometric Determination of Ca], TCI B0998 40070-59-5 Bromoxylenol Blue, TCI C0008 3147-14-6 Calmagite [Metal indicator for Ca, Mg etc.], TCI B0817 5833-18-1 Ethyl Bis(2,4-dinitrophenyl)acetate, TCI C0245 4430-20-0 Chlorophenol Red.

Pay attention to the pH or pM range at which the indicator changes color, its sensitivity to the target metal ion, and the purity and physical form (powder or solution) of the reagent. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
