82-46-2 Usage
Description
1,5-DICHLOROANTHRAQUINONE is a yellow powder that serves as an important intermediate in the production of vat dyes and disperse blue dyes. It is also used as a reagent in the preparation of anthraquinones, which possess antitumor activities.
Uses
Used in Dye Industry:
1,5-DICHLOROANTHRAQUINONE is used as an intermediate for the production of vat dyes and disperse blue dyes, contributing to the coloration and quality of various textiles and materials.
Used in Pharmaceutical Industry:
1,5-DICHLOROANTHRAQUINONE is used as a reagent in the preparation of anthraquinones, which have antitumor activities. This makes it a valuable component in the development of cancer treatments and therapies.
Used in Chemical Research:
1,5-DICHLOROANTHRAQUINONE undergoes a solid-state transformation at 470 K, with two modifications exhibiting different properties above and below the transition temperature. This characteristic makes it an interesting subject for chemical research and the study of phase transitions and material properties.
Check Digit Verification of cas no
The CAS Registry Mumber 82-46-2 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 2 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 82-46:
(4*8)+(3*2)+(2*4)+(1*6)=52
52 % 10 = 2
So 82-46-2 is a valid CAS Registry Number.
