S-3,6-bis(2-chloroethyl)piperazine-2,5-dione, also known as Thiotepa, is a chemical compound with the molecular formula C7H13Cl2N3O2. It is a nitrogen mustard alkylating agent, which is a type of chemotherapy drug used to treat various types of cancer, including bladder, breast, lung, and ovarian cancer. Thiotepa works by cross-linking DNA strands, preventing cell division and ultimately leading to cell death. It is typically administered intravenously or as a bladder instillation. Due to its potential side effects, such as bone marrow suppression and increased risk of secondary cancers, it is usually reserved for patients with advanced or recurrent cancers.

5394-22-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5394-22-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,9 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5394-22:
(6*5)+(5*3)+(4*9)+(3*4)+(2*2)+(1*2)=99
99 % 10 = 9
So 5394-22-9 is a valid CAS Registry Number.

Paragraph 0062; 0064; 0069; 0071; 0074; 0076; 0079; 0081, (2018/09/28)

The invention belongs to the technical field of organic compound synthesis and relates to a preparation method of fine glufosinate, in particular to a preparation method of fine glufosinate with L-homoserine as a raw material. According to the preparation method of fine glufosinate, L-homoserine prepared through a biological fermentation method serves as an initial raw material, L-3,6-di(2-halogenethyl)-2,5-diketopiperazine is prepared through the steps such as azeotropic dehydration and halogenation, a Serhiy Arbuzov reaction is conducted between L-3,6-di(2-halogen ethyl)-2,5-diketopiperazine and methyl phosphonic acid dibutyl, and fine glufosinate is prepared through a hydrolysis reaction. Compared with an existing preparation technology, the preparation method of fine glufosinate has the advantages that the total yield of fine glufosinate is greatly increased, the technological process is simple, and fine glufosinate is suitable for industrial production.
