1325-65-1 Usage
Preparation
in reflux conditions (or a little take pressure), in sodium hydroxide solution (E)-2-(2-sulfo-4-nitrostyryl)-5-nitrobenzenesulfonic acid with ?2-Aminobenzenesulfonic acid?diazotization and Naphthalen-1-amine coupled with heating products. Reaction to the different proportion of material that get different commodity dye.Flammability and Explosibility
NonflammableProperties and Applications
dark red yellow light. Soluble in water for orange brown, slightly soluble in alcohol. The strong sulfuric acid for blue-ray in black and Gray light black, dilute for yellow brown to olive after brown. The dye solution to join strong hydrochloric acid have yellow olive brown precipitation; Add thick sodium hydroxide solution for palm light orange.

The CAS Registry Mumber 1325-65-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,2 and 5 respectively; the second part has 2 digits, 6 and 5 respectively.Calculate Digit Verification of CAS Registry Number 1325-65:
(6*1)+(5*3)+(4*2)+(3*5)+(2*6)+(1*5)=61
61 % 10 = 1
So 1325-65-1 is a valid CAS Registry Number.
