(2,4-dichloro-3-fluoro-phenoxy)-acetic acid, also known as 2,4-dichlorophenoxyacetic acid (2,4-D), is a widely used synthetic auxin-type herbicide. It is a chlorophenoxy herbicide that selectively controls broadleaf weeds and woody plants in various crops, such as cereals, corn, and pastures. 2,4-D works by mimicking the action of plant hormones, causing uncontrolled growth and eventually leading to the death of the targeted weeds. The chemical structure consists of a 2,4-dichlorophenoxy group attached to an acetic acid chain, with a fluorine atom at the 3-position of the phenoxy ring. It is a white crystalline solid with a melting point of 138-140°C and is soluble in water, ethanol, and acetone. Due to its effectiveness and low cost, 2,4-D has been a popular choice for weed control since its introduction in the 1940s. However, concerns about its potential environmental and health impacts have led to ongoing research and regulations regarding its use.

395-27-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 395-27-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,9 and 5 respectively; the second part has 2 digits, 2 and 7 respectively.Calculate Digit Verification of CAS Registry Number 395-27:
(5*3)+(4*9)+(3*5)+(2*2)+(1*7)=77
77 % 10 = 7
So 395-27-7 is a valid CAS Registry Number.
