105512-06-9 Usage
Description
Clodinafop-propargyl is a foliar-absorbed aryloxyphenoxypropionate herbicide which has the capacity to inhibit the lipid biosynthesizing enzyme, acetyl coenzyme-A-carboxylase.Clodinafop-propargyl is a member of the Oxyphenoxy acid ester chemical class, which includes the active ingredients fluazifop-butyl, fenoxaprop-ethyl, diclofop methyl, quizalofop-ethyl and haloxyfop-methyl.
Chemical Properties
Pure Clodinafop-propargyl is colorless crystal, vapor pressure (25℃)3.19×10-3mPa, Solubility (25℃): water 4.0mg/L, ethyl alcohol 97 mg/L, acetone 880 mg/L, methyl benzene 690mg/L, n-hexane 0.0086 mg/L. Distribution coefficient (octane/water): KOWlogP=3.9(25℃). Clodinafop-propargyl can inhibit the synthesis of ester-like biology. It can be used to control amur foxtail, oat grass, avena sterilis, green bristlegrass and other weeds.
Uses
Different sources of media describe the Uses of 105512-06-9 differently. You can refer to the following data:
1. Clodinafop-propargyl is a member of the aryloxyphenoxy propionate chemical family. It acts as a systemic herbicide that acts on post-emergent weeds such as selected grasses. It does not act on broad leaved weeds. It is applied to the foliar parts of the weeds and is absorbed through the leaves. This foliar acting grass weed killer is translocated to the meristematic growing points of the plant where it interferes with the production of fatty acids required for plant growth.Grass weeds controlled include wild oats, rough meadow-grass, green foxtail, barnyard grass, Persian darnel, volunteer canary seed. It also provides moderate control of Italian rye-grass. It is suitable for use on the following crops – all varieties of wheat, autumn-sown spring wheat, rye, triticale and durum wheat.
2. Herbicides for weed control in wheat.
Definition
ChEBI: A carboxylic ester resulting from the formal condensation of the carboxy group of clodinafop with the hydroxy group of prop-2-yn-1-ol. It is widely used as a herbicide for the control of annual grass weeds in cereal crops.
Mode of action
Clodinafop-propargyl is to inhibit the activity of acetyl-CoA carboxylase in plants. It is a systemic conductive herbicide, absorbed by the leaves and sheaths of plants, transmitted by phloem, and accumulated in meristems of plants. In this case, acetyl-CoA carboxylase is inhibited, and fatty acid synthesis is stopped. So cell growth and division cannot proceed normally, and lipid-containing structures such as membrane systems are destroyed, leading to plant death.
Toxicity evaluation
a) Mammalian toxicity : WHO Classification : Class III slightly hazardous”b) Environmental toxicity : It is non-toxic to fish, birds and bees.Shelf life :Two years under normal storage conditions (Tech grade and Formulation)
Check Digit Verification of cas no
The CAS Registry Mumber 105512-06-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,5,1 and 2 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 105512-06:
(8*1)+(7*0)+(6*5)+(5*5)+(4*1)+(3*2)+(2*0)+(1*6)=79
79 % 10 = 9
So 105512-06-9 is a valid CAS Registry Number.
