17894-99-4 Usage
General Description
1-Naphthylamine-4,6,8-trisulfonic acid, also known as H-acid, is an organic compound extensively used as an intermediate in the synthesis of dyes for textiles and paper. 1-Naphthylamine-4,6,8-trisulfonic acid is derived from Naphthalene, a common ingredient in mothballs and insect repellents. Being trisulfonated, it is highly soluble in water and often presents as a yellow or golden-brown powder. Frequent exposure or handling can be hazardous due to its toxic and potentially carcinogenic nature. Despite its risks, it remains widely utilized in industrial operations due to its potent coloring properties and ability to bind strongly to fibers and other materials.
Check Digit Verification of cas no
The CAS Registry Mumber 17894-99-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,8,9 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 17894-99:
(7*1)+(6*7)+(5*8)+(4*9)+(3*4)+(2*9)+(1*9)=164
164 % 10 = 4
So 17894-99-4 is a valid CAS Registry Number.

-
, (2008/06/13)
An asymmetric dioxazine compound of the following formula in the free acid form, STR1 wherein R is hydrogen, halogen, sulfo or alkoxy, R1, R2 and R3 are each hydrogen or alkyl, X1 and X2 are each hydrogen, halogen, alkyl, alkoxy or phenoxy, Y is alkylene, phenylene or naphthylene, Z is --SO2 CH=CH2, --SO2 CH2 CH2 OSO3 H or the like, V is hydrogen, alkyl, acyl or substituted triazinyl, and Q is halogen, alkoxy, amino or a group similar to that of STR2 provided that R is hydrogen, and Q is amino or a group similar to that of STR3 when V is substituted triazinyl, which is useful for dyeing or printing fiber materials to give dyed or printed products of a brilliant blue color superior in fastness properties, particularly those such as chlorine fastness with superior build-up property.
