2349-71-5 Usage

General Description

2-Isopropylhydroquinone is a chemical compound with the molecular formula C9H12O2. It is a derivative of hydroquinone and is commonly used as an antioxidant and stabilizer in the food industry, particularly in fats and oils. It works by preventing the formation of free radicals and inhibiting the oxidation of food products, thereby extending their shelf life and maintaining their quality. 2-Isopropylhydroquinone is considered safe for use in food and is approved by the FDA for use as a preservative in certain food products. However, it is important to note that excessive consumption of this chemical can potentially lead to adverse health effects, and it is therefore regulated in terms of its maximum allowable limits in food products.

Check Digit Verification of cas no

The CAS Registry Mumber 2349-71-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,4 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2349-71:
(6*2)+(5*3)+(4*4)+(3*9)+(2*7)+(1*1)=85
85 % 10 = 5
So 2349-71-5 is a valid CAS Registry Number.

Iron-catalyzed arene C-H hydroxylation

Cheng, Lu,Wang, Huihui,Cai, Hengrui,Zhang, Jie,Gong, Xu,Han, Wei

, p. 77 - 81 (2021/10/05)

The sustainable, undirected, and selective catalytic hydroxylation of arenes remains an ongoing research challenge because of the relative inertness of aryl carbon-hydrogen bonds, the higher reactivity of the phenolic products leading to over-oxidized by-products, and the frequently insufficient regioselectivity. We report that iron coordinated by a bioinspired L-cystine-derived ligand can catalyze undirected arene carbon-hydrogen hydroxylation with hydrogen peroxide as the terminal oxidant. The reaction is distinguished by its broad substrate scope, excellent selectivity, and good yields, and it showcases compatibility with oxidation-sensitive functional groups, such as alcohols, polyphenols, aldehydes, and even a boronic acid. This method is well suited for the synthesis of polyphenols through multiple carbon-hydrogen hydroxylations, as well as the late-stage functionalization of natural products and drug molecules.

Secondary alcohols act as better nucleophiles than primary alcohols in the lipase-catalyzed regioselective deacylation of dihydroxybenzenes acylated at both phenolic hydroxyls

Miyazawa, Toshifumi,Hamada, Manabu,Morimoto, Ryohei,Murashima, Takashi,Yamada, Takashi

, p. 8334 - 8337 (2008/03/14)

Candida antarctica lipase B (CAL-B) was found to be highly regioselective as well as active in the deacylation of resorcinols and hydroquinones acylated at both phenolic hydroxyls. Contrary to expectation, secondary alcohols acted as better nucleophiles than primary alcohols in these enzymatic deacylations.
