6373-31-5 Usage
Description
6,10,12-trichloronaphth[2,3-c]acridine-5,8,14(13H)-trione is a red light purple powder that is insoluble in water but soluble in 1,2,3,4-tetrahydronaphthalene and xylene. It turns orange in concentrated sulfuric acid and forms a red purple precipitate upon dilution. It exhibits alkaline reduction leuco for purple and acid reduction leuco for brown.
Uses
Used in Textile Industry:
6,10,12-trichloronaphth[2,3-c]acridine-5,8,14(13H)-trione is used as a dye for viscose fabric dyeing and printing. It is unfavorable for discharge printing but can be used for white discharge. It has a higher direct sex on cotton and can also be used for dyeing wool and silk.
Used in Dye Fastness Testing:
6,10,12-trichloronaphth[2,3-c]acridine-5,8,14(13H)-trione is used in testing for ironing fastness, chlorine bleach, light fastness, mercerized, oxygen bleach, and soaping. The fastness ratings for these tests are as follows:
Ironing Fastness: ISO 4-5, AATCC 4
Chlorine bleach: ISO 4-5, AATCC 4-5
Light Fastness: ISO 8, AATCC 7
Mercerized: N/A
Oxygen bleach: ISO 4, AATCC 4
Soaping: ISO 4, AATCC 4-5

Check Digit Verification of cas no
The CAS Registry Mumber 6373-31-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,7 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6373-31:
(6*6)+(5*3)+(4*7)+(3*3)+(2*3)+(1*1)=95
95 % 10 = 5
So 6373-31-5 is a valid CAS Registry Number.
