Fluorescein is widely used as a green fluorescence dye and is known to exhibit excellent absorption and emission properties. Halogenated fluoresceins, represented by Tetraiodofluorescein [T0124], show a red shift in excitation wavelength and fluorescence wavelength compared to fluorescein. T0124 has been reported to be applied to organic photocatalytic reactions due to its excellent photocatalytic performance of iodine on the xanthene ring.

We are proud to present the tert-butyl esterification of N-acetyl-L-phenylalanine using N,N-DMF di-tert-butyl acetal [D1303].

We introduce to present reductive amination reaction of m-anisaldehyde using sodium triacetoxyborohydride [S0394] and dimethylamine hydrochloride.

We are proud to present the condensation reaction of 4-bromobenzoic acid and morpholine using the capsule reagent [R0294]. This reagent can eliminate the need for weighing. Each capsule contains 0.30 mmol of DMT-MM, a condensing agent.

Released in November 2024, TCI's latest issue features Prof. Shigeru Yamago’s article “Organotellurium-Mediated Radical Polymerization (TERP)” and Teacher Hiroyuki Onuki's chemistry chat “When a Teacher Is at a Loss in High School”.
