5209-33-6 Usage
Description
5-Chloroacenaphthene is a chlorinated derivative of acenaphthene, a polycyclic hydrocarbon. It is characterized by the presence of a chlorine atom in its molecular structure, which contributes to its unique properties and potential applications.
Uses
Used in Plant Science:
5-Chloroacenaphthene is used as a polyploidizing agent in the field of plant science. Its application reason is to induce polyploidy in plants, which can lead to increased vigor, higher yields, and improved resistance to diseases and environmental stresses.
The use of 5-Chloroacenaphthene as a polyploidizing agent can be particularly beneficial in agriculture, where the development of plants with enhanced characteristics can significantly improve crop production and quality. By inducing polyploidy, this compound has the potential to contribute to the advancement of plant breeding and the cultivation of more robust and productive plant varieties.
Check Digit Verification of cas no
The CAS Registry Mumber 5209-33-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,0 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5209-33:
(6*5)+(5*2)+(4*0)+(3*9)+(2*3)+(1*3)=76
76 % 10 = 6
So 5209-33-6 is a valid CAS Registry Number.

A library containing 10 air-stable NiIIX(Aryl)(PCy3)2 complexes as precatalysts (X = Cl, Br, OTs, OMs, aryl = 1-naphthyl, 2-naphthyl; X = Cl, 1-acenaphthenyl, 1-(2-methoxynaphthyl), 9-phenanthrenyl, 9-anthracyl) was synthesized and demonstrated to quantitatively cross-couple 2-methoxyphenyl dimethylsulfamate with methyl 4-(5,5-dimethyl-1,3,2-dioxaborinane-2-yl)benzoate at 23 °C in dry THF in the presence of K3PO4(H2O)3.2 in less than 60 min. Lower or higher amounts of H2O in K3PO4 and as received THF mediate the same transformation in a maximum three times longer reaction time.
