General Description
2-methyl-2-(4-chlorophenyl)-1,3-propanediol, also known as triclosan, is a synthetic chemical commonly used as an antibacterial and antifungal agent in personal care products and household items such as soaps, toothpaste, and cleaning products. It is known for its ability to kill and inhibit the growth of bacteria and fungi, making it popular in products designed to promote hygiene and prevent the spread of infectious diseases. However, triclosan has been the subject of controversy due to concerns about its potential negative effects on human health and the environment. Research has suggested that it may contribute to antibiotic resistance and disrupt hormone function, leading to regulatory restrictions on its use in some countries. Additionally, triclosan has been found to accumulate in the environment and has been detected in the bodies of humans and wildlife, raising concerns about its potential impact on ecosystems.
Check Digit Verification of cas no
The CAS Registry Mumber 2109-24-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,0 and 9 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2109-24:
(6*2)+(5*1)+(4*0)+(3*9)+(2*2)+(1*4)=52
52 % 10 = 2
So 2109-24-2 is a valid CAS Registry Number.

Production process of 2-methyl-2-(4-chlorphenyl)-1, 3-propylene glycol
-
Paragraph 0031-0034, (2020/07/12)
The invention discloses a production process of 2-methyl-2-(4-chlorphenyl)-1, 3-propylene glycol. The process comprises the following steps: taking p-chloroiodobenzene and diethyl malonate as initialraw materials; firstly, subjecting the p-chloroiodobenzene and diethyl malonate to coupling reaction to prepare a compound 3; carrying out alkylation reaction on the compound 3 and methyl iodide to obtain a compound 4; reacting the compound 4 with lithium aluminum hydride to obtain a 2-methyl-2-(4-chlorphenyl)-1, 3-propylene glycol crude product; and finally, subjecting the 2-methyl-2-(4-chlorphenyl)-1, 3-propylene glycol to a recrystallization procedure, thus obtaining the target product 2-methyl-2-(4-chlorphenyl)-1, 3-propylene glycol.
