Description
TRIMETHYL 4-HYDROXYORTHOBENZOATE, commonly known as methylparaben, is a chemical compound belonging to the paraben family. It is widely recognized for its preservative properties in various industries, including pharmaceuticals, personal care products, and food. Methylparaben effectively inhibits the growth of bacteria and fungi, thereby extending the shelf life of products. Additionally, it serves as a fragrance ingredient and a UV filter in sunscreen products. Despite its widespread use, there is ongoing debate regarding the safety of parabens, with concerns about their potential hormonal disruption and association with certain health conditions, leading to a growing interest in alternative preservatives.

Check Digit Verification of cas no
The CAS Registry Mumber 27689-95-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,6,8 and 9 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 27689-95:
(7*2)+(6*7)+(5*6)+(4*8)+(3*9)+(2*9)+(1*5)=168
168 % 10 = 8
So 27689-95-8 is a valid CAS Registry Number.

Synthesis of esters by selective methanolysis of the trifluoromethyl group
Ramig, Keith,Englander, Miriam,Kallashi, Florida,Livchits, Lilia,Zhou, Jessica
, p. 7731 - 7734 (2002)
The trifluoromethyl group of certain compounds containing one or two trifluoromethyl groups can be converted to the carbomethoxy group by treatment with sodium methoxide followed by aqueous acidic work-up. α-Trifluoromethyl esters can be obtained by selective methanolysis of the 1,1,1,3,3,3-hexafluoroisopropyl group in some cases. The structural requirements for the transformation are delineated, and a mechanistic study confirms the proposed mechanism, a dehydrofluorination-addition-elimination process.
