Trans-4,4'-Dichlorocrotonanilide, also known as DCPA, is a widely used herbicide belonging to the chloroacetamide family. It is an effective pre-emergence and early post-emergence control agent for various annual grasses and broadleaf weeds in agricultural crops, such as corn, soybeans, and cotton. DCPA works by inhibiting the growth of root systems and disrupting the cell division process in plants, ultimately leading to their death. The chemical structure of trans-4,4'-dichlorocrotonanilide consists of a dichloroaniline moiety attached to a crotonanilide group, which contributes to its herbicidal properties. Due to its effectiveness and low mammalian toxicity, DCPA has been a popular choice for weed control in various agricultural settings. However, concerns about its potential environmental impact and persistence in soil have led to increased scrutiny and regulations on its use in some regions.
The CAS Registry Mumber 6090-84-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,0,9 and 0 respectively; the second part has 2 digits, 8 and 4 respectively. Calculate Digit Verification of CAS Registry Number 6090-84: (6*6)+(5*0)+(4*9)+(3*0)+(2*8)+(1*4)=92 92 % 10 = 2 So 6090-84-2 is a valid CAS Registry Number.
