(4-fluoro-phenoxy)-acetic acid octyl ester, also known as octyl 4-fluorophenoxyacetate, is a synthetic chemical compound with the molecular formula C16H19FO3. It is an ester derivative of (4-fluoro-phenoxy)-acetic acid, where an octyl group is attached to the carboxylic acid moiety. (4-fluoro-phenoxy)-acetic acid octyl ester is characterized by its potential use as a plant growth regulator, specifically as a selective herbicide. It works by mimicking the action of natural auxins, leading to uncontrolled growth in susceptible plants and ultimately causing their death. The 4-fluoro substitution on the phenoxy ring provides a degree of selectivity, making it effective against certain weed species while having a lower impact on desired crops. This chemical is an example of the application of fluorine chemistry in agrochemicals, where the introduction of a fluorine atom can significantly alter the biological activity and selectivity of a compound.
The CAS Registry Mumber 1542-86-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,4 and 2 respectively; the second part has 2 digits, 8 and 6 respectively. Calculate Digit Verification of CAS Registry Number 1542-86: (6*1)+(5*5)+(4*4)+(3*2)+(2*8)+(1*6)=75 75 % 10 = 5 So 1542-86-5 is a valid CAS Registry Number.
