110488-70-5 Usage
Description
Different sources of media describe the Description of 110488-70-5 differently. You can refer to the following data:
1. Dimethomorph is a cinnamic acid derivative and a member of the morpholine chemical family. Dimethomorph is a mixture of E- and Z-isomers in the ratio of about 1:1 and only the Z-isomer has the fungicidal activity. It fungicidal activity works by the inhibition of sterol (ergosterol) synthesis.
Dimethomorph is a systemic fungicide to protect against various fungal pathogens in vines and other crops. Dimethomorph is used to against downy mildews, late blights, anthracnose, septoria leaf spot, crown rot, and root rot for curbubits, grapevines, head lettuce, onions, potatoes, tomatoes, and fruit including blackberries, raspberries, strawberries.
2. Dimethomorph is a morpholine fungicide that inhibits fungal cell wall formation. It inhibits mycelial growth of the oomycete fungi P. citrophthora, P. parasitica, P. capsici, and P. infestans (EC50s = 0.14, 0.38, <0.1, and 0.16-0.3 μg/ml, respectively) but is less active against the green algae species C. vulgaris or S. obliquus in vitro (EC50s = 47.46 and 44.87 μg/ml, respectively). It inhibits androgen receptor (AR) activity in a reporter assay in MDA-kb2 human breast cancer cells but not in a yeast antiandrogen screen (IC20s = 0.263 and 38.5 μM, respectively). It is not toxic to rats (LD50 = 3,900 mg/kg) or goldfish (C. auratus; LC50 = >32 μg/ml).

Uses
Different sources of media describe the Uses of 110488-70-5 differently. You can refer to the following data:
1. Agricultural fungicide.
2. Dimethomorph is a systemic fungicide which exhibits protectant,
curative and antisporulant activities. It is active against fungal diseases
such as leaf blight, downy mildew, damping off and foot-rot caused by
Phytophthora spp. in/on grapes, potatoes and tomatoes.
Definition
ChEBI: A mixture of (E)- and (Z)-dimethomorph in an unspecified ratio. It is used as a systemic fungicide used on vines, potatoes, and greenhouse crops; only the Z isomer has fungicidal activity.
Agricultural Uses
Fungicide: A systemic fungicide that protects crops from mold.
It also kills mold and prevents their spread; controls late
blight on tomatoes; and is used as a wood preservative to
control downey mildew.

Metabolic pathway
Limited data are available in the open literature. Information presented in
this summary is abstracted from the data evaluation published by the
Pesticide Safety Directorate (PSD, 1994). Dimethomorph is a (1:l) mixture
of the E- and Z-isomers. The Z-isomer has been shown to have all the
intrinsic biological activities. The isomerisation of the E- and Z-isomers
was observed when resolved isomers were exposed to UV light. Dimethomorph
undergoes extensive degradation and metabolism in soil,
plants and animals. The major metabolic pathway is the O-demethylation
of one of the phenolic methoxy moieties to the corresponding phenols
and conjugates. Other metabolic reactions include the oxidation of one of
the CH2 moieties of the morpholine ring and the cleavage/opening of
the morpholine ring (Scheme 1).
Degradation
Dimethomorph (1) is hydrolytically stable with no observable degradation
in pH 4-9 buffered solutions at 70-90 °C for up to 10 weeks.
Degradation occurred when dimethomorph in pH 5 buffer solution was
irradiated under Hanau Suntest apparatus (<290 nm) at 25 °C. The calculated
aqueous photolytic degradation half-life (DT50) was ca. 25-28 days of
continuous irradiation, No sigruficant degradation product (>7% of the
applied radioactivity) was identified.
Check Digit Verification of cas no
The CAS Registry Mumber 110488-70-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,4,8 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 110488-70:
(8*1)+(7*1)+(6*0)+(5*4)+(4*8)+(3*8)+(2*7)+(1*0)=105
105 % 10 = 5
So 110488-70-5 is a valid CAS Registry Number.

Method for catalytically synthesizing dimethomorph by using Lewis base
-
Paragraph 0016-0019, (2021/03/18)
The invention relates to the technical field of dimethomorph production, and particularly discloses a method for catalytically synthesizing dimethomorph by using a Lewis base. According to the method,benzophenone and acetylmorpholine are subjected to a low-temperature reaction, an intermediate-state product is prepared in the presence of a solvent and the Lewis base, and then an elimination reaction is carried out under the high-temperature condition to remove one molecule of water, so that the product is obtained. The method has the advantages of concise and reliable synthetic route, low consumption of the raw material acetylmorpholine, easy control of the reaction, low cost of the obtained product, less generation of three wastes, and high economic and environmental protection values.
Dimethomorph production method

, (2018/06/15)
The invention discloses a dimethomorph production method in the technical field of pesticide production. The production method comprises: 1) synthesizing veratrole; 2) synthesizing 3,4-dimethoxy-4-chloro-benzophenone; 3) synthesizing acetylmorpholine; and 4) synthesizing dimethomorph. Sodium tert-butoxide is taken as a basic catalyst for synthesizing dimethomorph from 3,4-dimethoxy-4-chloro-benzophenone and acetylmorpholine, and a sodium hydroxide solution is used to perform alkali washing on a reactant in a reaction vessel. Sodium hydroxide has a catalytic effect on synthesis of dimethomorphfrom 3,4-dimethoxy-4-chloro-benzophenone and acetylmorpholine. The defect that the catalytic effect of sodium tert-butoxide is gradually reduced due to unstable chemical property of sodium tert-butoxide and degradation of sodium tert-butoxide when sodium tert-butoxide comes into water is overcome. The dimethomorph product is improved in conversion rate and purity.
