1503-48-6 Usage
Uses
Used in Ink and Paint Industries:
Quinacridonequinone is used as a pigment in the ink and paint industries for its ability to produce intense and long-lasting hues, particularly in red, violet, and maroon shades. Its high heat stability and resistance to fading make it ideal for applications where exposure to high temperatures is likely.
Used in Color Production:
In the color production industry, Quinacridonequinone serves as a pigment for creating vibrant and durable colors in various products. Its high level of lightfastness ensures that the colors remain true and consistent over time, even when exposed to sunlight or other environmental factors.
Used in Plastics and Textiles:
Quinacridonequinone is also utilized in the plastics and textiles industries as a colorant. Its heat stability and resistance to fading make it suitable for use in products that may be subjected to high temperatures during manufacturing or use, such as automotive parts, outdoor textiles, and heat-resistant plastics.
Used in Art Supplies:
In the art supplies industry, Quinacridonequinone is used as a pigment in paints and inks for artists. Its intense colors and lightfastness make it a preferred choice for creating long-lasting and vibrant artwork.
Used in Cosmetics:
Quinacridonequinone is employed in the cosmetics industry as a colorant in various products, such as lipsticks, eyeshadows, and blushes. Its ability to produce vivid and long-lasting colors, along with its heat stability, makes it an ideal choice for cosmetic formulations.
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.

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.
