33229-34-4 Usage
Chemical Properties
Blue-violet crystal powder
Uses
2,2′-[4-(2-Hydroxyethylamino)-3-nitrophenylimino]diethanol may be employed to improve the visibility of self-healing ureidopyrimidinone (UPy) hydrogel (poly(ethylene glycol) containing bifunctional UDP groups).
General Description
Dark blue to dark brown microcrystalline powder.
Air & Water Reactions
May be sensitive to prolonged exposure to air. Slow oxidation. Insoluble in water.
Fire Hazard
Flash point data for 2,2'-((4-((2-Hydroxyethyl)amino)-3-nitrophenyl)imino)bisethanol are not available; however, 2,2'-((4-((2-Hydroxyethyl)amino)-3-nitrophenyl)imino)bisethanol is probably combustible.
Flammability and Explosibility
Nonflammable
Check Digit Verification of cas no
The CAS Registry Mumber 33229-34-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,2,2 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 33229-34:
(7*3)+(6*3)+(5*2)+(4*2)+(3*9)+(2*3)+(1*4)=94
94 % 10 = 4
So 33229-34-4 is a valid CAS Registry Number.
