Description
Sparfosic, also known as N-(3-chloro-2-propen-1-yl)-2,6-dinitro-4-trifluoromethylbenzamine, is a chemical compound that functions as a selective pre-emergence herbicide. It is specifically designed to control annual grasses and broadleaf weeds in a variety of crops. Sparfosic operates by inhibiting the enzyme protoporphyrinogen oxidase (PPO) in plants, which ultimately results in the death of the weeds. This herbicide is highly effective in weed control and has low toxicity to mammals, making it a popular and safe choice for agricultural applications.
Used in Agricultural Industry:
Sparfosic is used as a selective pre-emergence herbicide for controlling annual grasses and broadleaf weeds in various crops. Its application reason is its ability to inhibit the enzyme protoporphyrinogen oxidase (PPO) in plants, leading to their death, while maintaining low toxicity to mammals. This makes Sparfosic a popular and safe choice for agricultural use, ensuring effective weed control without posing significant risks to the environment or human health. However, it is crucial to handle and apply Sparfosic with care to avoid potential harm if not used properly.
Check Digit Verification of cas no
The CAS Registry Mumber 51321-79-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,3,2 and 1 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 51321-79:
(7*5)+(6*1)+(5*3)+(4*2)+(3*1)+(2*7)+(1*9)=90
90 % 10 = 0
So 51321-79-0 is a valid CAS Registry Number.

A new, efficient, two step procedure for the preparation of the antineoplastic agent sparfosic acid
Morris, Angela D.,Cordi, Alex A.
, p. 1259 - 1266 (2007/10/03)
Sparfosic acid can easily be prepared in two steps and in excellent yield from condensation of the commercially available starting materials L-aspartic acid di-tert-butyl ester hydrochloride and diethylphosphonoacetic acid, followed by a quadruple deprotection of acidic functions under mild conditions using bromotrimethylsilane.
Preparation of N-(phosphonoacetyl)-L-aspartic acid

, (2008/06/13)
Improved methods for preparation of the tetrasodium and disodium salts ofN-(phosphonoacetyl)-L-aspartic acid (PALA) are disclosed. The present methods are well suited for preparation of these products in large amounts. Particular aspects of these methods include: (1) the initial preparation of phosphonoacetyl chloride which is employed in producing the desired products; and (2) the use of anhydrous conditions for preparation and isolation of the cyclohexylammonium salt of dibenzyl PALA.
