38559-81-8 Usage
General Description
(4-butoxyphenoxy)acetic acid, also known as 4-BPA, is a synthetic herbicide used to control broadleaf and grassy weeds in a variety of crops. It works by disrupting plant growth and development, leading to the eventual death of the targeted weeds. 4-BPA is typically applied as a foliar spray and is absorbed through the leaves of the plants. It is a selective herbicide, meaning it targets specific types of weeds while leaving desired crops relatively unharmed. However, it is important to use 4-BPA with caution, as it can be harmful to aquatic organisms and has the potential to leach into groundwater. Proper application and adherence to safety guidelines are essential when using this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 38559-81-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,5,5 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 38559-81:
(7*3)+(6*8)+(5*5)+(4*5)+(3*9)+(2*8)+(1*1)=158
158 % 10 = 8
So 38559-81-8 is a valid CAS Registry Number.

Paragraph 0073-0076, (2021/09/15)
The invention relates to the field of separation and enrichment of metals, in particular to an extractant, a preparation method and application thereof. The preparation method comprises the followingsteps that a phenol compound reacts with a halogenated carboxylic acid derivative or halogenated carboxylate in a solvent, then acidifying is carried out, and the phenoxy carboxylic acid extractant issynthesized. The prepared extractant can be used for enriching rare earth in rare earth mineral leachate after being saponified by an alkaline compound; compared with the existing extractant, the extractant has the advantages of being higher in precipitation capacity, high in precipitation efficiency and large in precipitation particles, facilitating the separation of a rare earth extraction complex and a water phase and improving the production efficiency; and moreover, the extractant can further be used for selectively recovering/separating valuable metals from different industries.
