Carbamic acid, (2-chloro-4-pyrimidinyl)-, 1,1-dimethylethyl ester, commonly known as propazine, is a chemical compound that functions as a herbicide. It is designed to control the growth of various types of weeds, particularly broadleaf and grassy weeds, in agricultural settings. Propazine is typically applied as a spray or incorporated into granular formulations, making it a versatile tool for crop management. However, due to its potential environmental and health impacts, its use is subject to regulation in many countries to mitigate associated risks.

Uses

Used in Agricultural Industry:
Propazine is used as a herbicide for controlling the growth of broadleaf and grassy weeds in agricultural settings. It is applied as a spray or in granular formulations to ensure effective weed management, thereby promoting healthy crop growth and reducing competition for resources.
Used in Crop Management:
Propazine serves as a crucial component in crop management strategies, where it inhibits the growth of unwanted weeds that could otherwise hinder the development of desired crops. By controlling weed populations, propazine helps to maintain optimal growing conditions for crops, leading to increased yields and better crop quality.

Check Digit Verification of cas no

The CAS Registry Mumber 849751-48-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,9,7,5 and 1 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 849751-48:
(8*8)+(7*4)+(6*9)+(5*7)+(4*5)+(3*1)+(2*4)+(1*8)=220
220 % 10 = 0
So 849751-48-0 is a valid CAS Registry Number.

Photoreductive Removal of O-Benzyl Groups from Oxyarene N-Heterocycles Assisted by O-Pyridine-pyridone Tautomerism

Todorov, Aleksandar R.,Wirtanen, Tom,Helaja, Juho

, p. 13756 - 13767 (2017)

Facile photoreductive protocols have been developed to remove benzyl O-protective groups from oxyarene N-heterocycles at positions capable for 2-/4-O-pyridine-2-/4-pyridone tautomerism. Blue light irradiation, a [Ru] or [Ir] photocatalyst, and ascorbic acid in a water-acetonitrile solution debenzylates a variety of aryl N-heterocycles cleanly and selectively. Ascorbic acid has two functions in the reaction. On the one hand, it protonates the N-heterocycles that reduces their reduction potentials notably and on the other hand it acts as a sacrificial reductant. Reduction potentials and free energy barriers calculated at the CPCM-B3LYP/6-31+G? level can predict the reactivities of the studied substrates.
