Description
Cinmethylin, developed by Shell Chemical Company in the early 1980s, is a weed control agent specifically designed for monocotyledonous species. It is a member of the cineole eucalyptol family and functions as a pre-emergence grass herbicide.
Uses
Used in Agriculture:
Cinmethylin is used as a pre-emergence grass herbicide for controlling important grasses such as green foxtail (Setaria viridis) and barnyardgrass (Echinochloa crus-galli). It is also effective in suppressing the growth of several broadleaf weeds, including prickly sida (Sida spinosa) and velvetleaf (Abutilon theophrasti). This makes it a valuable tool in managing weed populations and maintaining healthy crop growth.
Pharmacology
Cinmethylin is active on several important grasses in
rice (Echinochloa spp., Cyperus spp., and Monochoria
vaginalis) at rates from 25 to 100 g ai/ha (5). Its chemical
and toxicological features (low persistence in environment
and low mammalian toxicity) generated a significant level
of interest in its use as a rice herbicide.
Metabolic pathway
When rats are administered 14C-cinmethylin orally, the
major route of its elimination is via urinary excretion. A
complex degradation pattern of cinmethylin is
observed and the metabolic pathways involve
hydroxylation, oxidation at the benzyl and cineol
portions, conjugation with glucuronic acid and glycine,
and cleavage of the ether linkage. When rats are
administered 14C-cinmethylin by stomach incubation,
two minor metabolites are identified as o-
(acetoxymethyl)benzoic acid and 9-(acetoxymethyl)-a-
carboxycinmethylin.
Check Digit Verification of cas no
The CAS Registry Mumber 87818-31-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,8,1 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 87818-31:
(7*8)+(6*7)+(5*8)+(4*1)+(3*8)+(2*3)+(1*1)=173
173 % 10 = 3
So 87818-31-3 is a valid CAS Registry Number.
