General Description

2,5-bis(4-chlorophenylamino)terephthalic acid is a chemical compound with two 4-chlorophenylamino groups attached to a terephthalic acid backbone. It is commonly used as a dye intermediate and has also been studied for its potential use in organic optoelectronic devices due to its electronic and optical properties. 2,5-bis(4-chlorophenylamino)terephthalic acid has been shown to exhibit excellent thermal and chemical stability, making it a promising material for a wide range of applications. Additionally, it has been investigated for its potential antioxidant and anti-inflammatory properties, with the goal of developing new therapeutic agents.

Check Digit Verification of cas no

The CAS Registry Mumber 41680-76-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,6,8 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 41680-76:
(7*4)+(6*1)+(5*6)+(4*8)+(3*0)+(2*7)+(1*6)=116
116 % 10 = 6
So 41680-76-6 is a valid CAS Registry Number.

Preparation method for quinacridone and derivatives of quinacridone

-

Paragraph 0036, (2017/08/29)

The invention relates to the field of synthesis of organic pigments and discloses a preparation method for quinacridone and derivatives of the quinacridone. The preparation method comprises the steps that dimethyl succinate generates sodium dimethyl succinylsuccinate (DMSS) through cyclic condensation under an effect of sodium methoxide, and then being acidized into DMSS; condensation reaction occurs between the DMSS and aniline or substituted aniline, an intermediate product generated during condensation is directly oxidized and dehydrogenated by sodium 3-nitrobenzene sulfonate to obtain an oxidative product; and finally coarse products of the quinacridone or the derivatives of the quinacridone are prepared from the oxidative product in a ring-closing mode under an effect of polyphosphoric acid, and finally finished products of the quinacridone or the derivatives of the quinacridone are obtained through pigmentation treatment.

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

Page/Page column 13-14, (2008/06/13)

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

-

, (2008/06/13)

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
