1503-48-6 Usage

General Description

Quinacridonequinone is a synthetic organic compound that is commonly used in the production of pigments for use in inks, paints, and other applications. It is part of the quinacridone family of pigments and is known for its bright and vivid colors, as well as its high level of lightfastness and resistance to fading. Quinacridonequinone is often used in the production of red, violet, and maroon pigments and is valued for its ability to produce intense and long-lasting hues. Additionally, it is known for its high heat stability and is often used in applications where exposure to high temperatures is likely.

Check Digit Verification of cas no

The CAS Registry Mumber 1503-48-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,0 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1503-48:
(6*1)+(5*5)+(4*0)+(3*3)+(2*4)+(1*8)=56
56 % 10 = 6
So 1503-48-6 is a valid CAS Registry Number.

Difluoroboron Chelation to Quinacridonequinone: A Synthetic Method for Air-Sensitive 6,13-Dihydroxyquinacridone via Boron Complexes

Moriya, Koichiro,Shimada, Ryohei,Ono, Katsuhiko

, p. 1452 - 1456 (2019)

This study aims to perform the chelation of difluoroboron (BF2) to quinacridonequinone (QQ). The resulting dark green solid was determined to be QA-BF2, which is a BF2 complex of 6,13-dihydroxyquinacridone (QA-OH), and not QQ-BF2, which is a BF2 complex of QQ. This result indicated that QQ-BF2 was first generated as an O,O-bidentate chelate, which immediately underwent a two-electron reduction to produce QA-BF2. This compound was converted to air-sensitive QA-OH by undergoing hydrolysis in argon. Since QA-OH has a strong electron-donating property, it easily produced QQ via air oxidation in the solution. QA-OH also acts as a reducing reagent for quinones. The crystal packing of QA-OH is a herringbone type with short π???π contacts, and a good hole mobility has been suggested by theoretical calculations. Herein, a new synthetic method from QQ to QA-OH using BF2 chelation and hydrolysis was proposed. QA-BF2 and QA-OH are useful organic functional pigments and reducing reagents.
