240409-02-3 Usage
General Description
2,4-Difluoro-DL-Phenylglycine is a chemical compound commonly used in the pharmaceutical industry. As an organic compound, it is characterized by the presence of two fluorine atoms and an alpha-amino acid within its structure. This artificial amino acid is often used in the synthesis of different types of drugs, specifically as a component in the production of antibiotics. It plays a critical role in inhibiting the growth of certain types of bacteria, hence its prevalence in specific drug formulas. It is also known for its stability and reactivity, though it should always be handled with care due to potential health and environmental risks.
Check Digit Verification of cas no
The CAS Registry Mumber 240409-02-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,0,4,0 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 240409-02:
(8*2)+(7*4)+(6*0)+(5*4)+(4*0)+(3*9)+(2*0)+(1*2)=93
93 % 10 = 3
So 240409-02-3 is a valid CAS Registry Number.

-
Page/Page column 14; 15, (2019/01/11)
The present invention relates to a.method for preparing intermediates of 4- methoxypyrrole derivatives. The preparation method according to the present invention has advantages that the production cost can be lowered by using inexpensive starting materials, a high-temperature reaction is not required as a whole, inexpensive and non-explosive reagents are used instead of (trimethylsilyl)diazomethane, and further an intermediate of 4-methoxypyrrole derivatives can be prepared as a whole at a high yield.
