General Description
A white slightly hygroscopic crystalline powder or lump solid with a mild chlorine-like odor. Said to have 85 percent available chlorine. Decomposes at 225°C. Moderately toxic by ingestion. May irritate skin and eyes. Active ingredient in household dry bleaches. Used in swimming pools as a disinfectant .
Air & Water Reactions
Slightly hygroscopic [Hawley]. Slightly soluble in water. May react with water releasing gaseous chlorine. If mixed with a small amount of water, the concentrated solution (with pH at about 2.0) may explode due to the evolution of unstable nitrogen trichloride. (explanation in Bretherick 5th ed.)
Reactivity Profile
TRICHLORO-S-TRIAZINETRIONE, [DRY, CONTAINING > 39% AVAILABLE CHLORINE] may react vigorously with ammonium compounds or hydrated salts. Prolonged exposure to heat may result in the vigorous decomposition with the rupture of containers. Accelerates the burning of combustible materials [AAR 1991]. May reactwith alcohols to yield alkyl hypochlorites that decompose in the cold and explode on exposure to sunlight or heat. Hypochlorites of tertiary alcohols are less unstable than those of secondary or primary alcohols [NFPA 491 M. 1991].

Check Digit Verification of cas no
The CAS Registry Mumber 87-90-1 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 87-90:
(4*8)+(3*7)+(2*9)+(1*0)=71
71 % 10 = 1
So 87-90-1 is a valid CAS Registry Number.

Paragraph 0027-0034, (2017/03/28)
The invention discloses a method for producing trichloro-isocyanuric acid by virtue of two-stage continuous chlorination. A production process of the method comprises first-stage chlorination reaction and second-stage chlorination reaction; an excessive amount of chlorine is fed into a second-stage reaction kettle, a cyanuric acid trisodium salt solution is continuously added into a first-stage reactor, the excessive amount of chlorine in the second-stage reaction kettle is sucked into the first-stage reactor for chlorination reaction by virtue of an ejection pump of a first-stage reaction system, and a reaction liquid overflows into the second-stage reaction kettle to continuously react to generate trichloro-isocyanuric acid. The chlorination reaction degree of materials inside the one-stage reactor and the chlorine feeding amount of the second-stage reaction kettle are controlled by virtue of the reaction temperature of the first-stage reactor. The method is small in amount of chlorination mother liquid and high in reaction efficiency, and a gas discharged from the first-stage reactor is free of chlorine. The time that the material is retained in the chlorination reaction system is short, so that side reaction can be reduced, the effective chlorine of a product is kept greater than 90%, and the yield is more than 86%.
