Method for preparing 2,5-di(substituted) arylamino terephthalic acid

The invention relates to a method for preparing 2,5-di(substituted) arylamino terephthalic acid by oxidizing 2,5-di(substituted) arylamino-3,6-dihydro-terephthalic acid ester. Hydrogen peroxide is adopted as an oxidizing agent in the method; the hydrogen peroxide is capable of completely oxidizing matter to be oxidized (the reactant conversion rate is high), and has better selectivity (the purity and the yield of a target object are both higher); furthermore, the hydrogen peroxide is converted into water after being oxidized, and a reaction system has no byproducts formed by over oxidation. Therefore, the method for preparing the 2,5-di(substituted) arylamino terephthalic acid, provided by the invention, is economic, friendly to environment and easy to control in reaction.

2,5-DI(METHOXYANILINO)TEREPHTHALIC ACID POLYMORPHS AND QUINACRIDONES REALIZED THEREFROM

2,5-di(p-methoxyanilino)terephthalic acid crystal types I and Il are made by controlling the pH during the recovery of the oxidized product of the condensation of dimethylsuccinyl succinate with p-methoxyaniline. The resulting 2,5-di(p- methoxyanilino)-terephthalic acid can be converted into 2,9-dimethoxyquinacridone or a solid solution thereof having controlled characteristics.

Quinacridone derivatives as labelling reagents for flurescence detection of bilogical materials

Disclosed are new quinacridone dye derivatives having characteristic fluorescence lifetimes. Also disclosed are methods for labelling target biological materials employing the quinacridone dyes and use of the labelled materials in biological assays. The quinacridone derivatives have the structure (I), in which Z1 and Z2 independently represent the atoms necessary to complete one ring, two fused ring, or three fused ring aromatic or heteroaromatic systems, each ring having five or six atoms selected from carbon atoms and optionally no more than two atoms selected from oxygen, nitrogen and sulphur; R3, R4, R5, R6, R7 and R8 are independently selected from hydrogen, halogen, amide, hydroxyl, cyano, nitro, mono- or di-nitro-substituted benzyl, amino, mono- or di-C1-C4 alkyl-substituted amino, sulphydryl, carbonyl, carboxyl, C1-C6 alkoxy, acrylate, vinyl, styryl, aryl, heteroaryl, C1-C20 alkyl, aralkyl, sulphonate, sulphonic acid, quaternary ammonium, the group —E—F and the group —(CH2—)nY; R1 and R2 are independently selected from hydrogen, mono- or di-nitro-substituted benzyl, C1-C20 alkyl, aralkyl, the group —E—F and the group —(CH2—)nY; E is a spacer group, F is a target bonding group; Y is selected from sulphonate, sulphate, phosphonate, phosphate, quaternary ammonium and carboxyl; and n is an integer from 1 to 6. The invention also relates to a set of different fluorescent quinacridone dye derivatives, each dye having a different fluorescence lifetime, the set of dyes being particularly useful for multiparameter analysis. 1
