2675-77-6 Usage
Description
Chloroneb was developed by Du Pont de Nemours Co.
in 1967. It differs from the compounds described above
in that it does not contain nitro-groups. In
common with other chlorobenzene fungicides, chloroneb
has a low mammalian toxicity and a significant
vapor pressure so that it was used as a soil fungicide in
the culture of beans, cucumber, and cotton (20). In contrast
with the nitrobenzene compounds, Phytophthora spp. are
rather sensitive to chloroneb. Pythium spp. vary
in sensitivity to chloroneb. Because of its low water
solubility, chloroneb is only very weakly systemic (21,22).

1. beige powder
2. Colorless crystalline solid. Musty odor
Definition

Fungicide: A systemic fungicide used to control snow mold on turf grass; used on cotton, sugar beets and bean seeds to control seedling disease. Not approved for use in EU countries. Registered for use in the U.S. except California
Trade name
CHLORAXYL? SEED TREATER; DELTA-COAT? II; DEMOSAN?; SOIL FUNGICIDE?-1823; TERSAN? SP; TERRANEB? SP; SOIL FUNGICIDE 1823?
Pharmacology
Chloroneb is not
effective against Fusarium but has a relatively broad
spectrum of activity compared with other compounds
that are specifically active against oomycetes (24). By
controlling Rhizoctonia solani, by seed-piece or in
furrow applications, chloroneb increased potato yields in
Texas (25).
Potential Exposure
An organochlorine/substituted benzene
systemic fungicide used to control snow mold on turf grass;
used on cotton, sugar beets and bean seeds to control seedling disease. Not approved for use in EU countries.

Waste Disposal
Do not discharge into drains
or sewers. Dispose of waste material as hazardous waste
using a licensed disposal contractor to an approved landfill.Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Incineration with
effluent gas scrubbing is recommended. Containers must be
disposed of properly by following package label directions
or by contacting your local or federal environmental control
agency, or by contacting your regional EPA office.
Check Digit Verification of cas no
The CAS Registry Mumber 2675-77-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,7 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2675-77:
(6*2)+(5*6)+(4*7)+(3*5)+(2*7)+(1*7)=106
106 % 10 = 6
So 2675-77-6 is a valid CAS Registry Number.

Homogeneous catalysis and selectivity in electrochemistry
Michman, Michael,Appelbaum, Lina,Gun, Jenny,Modestov, Alexander D.,Lev, Ovadia
, p. 4729 - 4737 (2015/04/27)
The relationship between homogeneous catalysis and electrochemistry is examined in light of two examples based on our work concerning (a) catalyst activation, regarding selective electrochemical C-H oxidation with RuIII/RuIV mediation, and (b) catalyst suppression, regarding controlling selectivity in electrochemical aromatic chlorination. The first example (a) deals with the role of catalysis at the working electrode. The electrochemical (EC) oxidation of specific hydrocarbons such as tetralin and indane is performed using tris(acetonitrile)ruthenium trichloride (Ru(CH3CN)3Cl3) as a mediator. The role of this mediator in the oxidation of tetralin has been reported. This homogeneous C-H activation by electron transfer (ET) is accompanied by the redox transitions of the mediator in the course of the catalytic oxidation, and these are the main points of interest here. Additional studies with a rotating ring disk electrode (RRDE) provided a follow-up of creation and recovery of RuIII/RuII and RuIII/RuIV species in the process. Using electrochemistry linked with electrospray ionization mass spectrometry (EC/ESI-MS) gave additional information on the structure of the reduced and oxidized forms of Ru(CH3CN)3Cl3 and the effect of water in the solvent on their lifetimes. The second example (b) of electrochlorination has been reported elsewhere and is brought up as complementary remarks. Aromatic electrophilic chlorination of 1,4-dimethoxy-2-tertbutylbenzene is autocatalyzed and unselective. The EC procedure provides a simple means to inhibit the catalytic runaway reaction. This example shows how the counter electrode affects catalysis and selectivity. (Figure Presented)
