Phenylparaben is used as a preservative in the cosmetic industry to ensure the safety and shelf life of products. It helps prevent the growth of harmful microorganisms that could cause infections or spoilage.
Used in Food Industry:
Phenylparaben is used as a preservative in the food industry to extend the shelf life of various products by inhibiting the growth of bacteria, molds, and yeast.
Used in Drug Delivery Systems:
Phenylparaben is used in the investigation of drug partition property in artificial sebum for the targeted delivery of therapeutic agents into the hair and sebaceous follicles. This application aims to improve the effectiveness of treatments for hair and skin conditions.
Used in Research and Development:
Phenylparaben is utilized in in vitro and molecular docking studies on the side chains of parabens as modulators of antiandrogenic activities. This research contributes to the understanding of the compound's potential effects on hormone regulation and its applications in the development of new medications.
Flammability and Explosibility
Notclassified
Contact allergens
This substance is one of the parabens family. Parabens are esters formed by p-hydroxybenzoic acid
and an alcohol. They are largely used as biocides in
cosmetics and toiletries, medicaments, or food. They
have synergistic power with other biocides. Parabens
can induce allergic contact dermatitis, mainly in
chronic dermatitis and wounded skin.
Check Digit Verification of cas no
The CAS Registry Mumber 17696-62-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,6,9 and 6 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 17696-62:
(7*1)+(6*7)+(5*6)+(4*9)+(3*6)+(2*6)+(1*2)=147
147 % 10 = 7
So 17696-62-7 is a valid CAS Registry Number.

Cleavage of Carboxylic Esters by Aluminum and Iodine
Sang, Dayong,Yue, Huaxin,Fu, Yang,Tian, Juan
, p. 4254 - 4261 (2021/03/09)
A one-pot procedure for deprotecting carboxylic esters under nonhydrolytic conditions is described. Typical alkyl carboxylates are readily deblocked to the carboxylic acids by the action of aluminum powder and iodine in anhydrous acetonitrile. Cleavage of lactones affords the corresponding ω-iodoalkylcarboxylic acids. Aryl acetylates undergo deacetylation with the participation of the neighboring group. This method enables the selective cleavage of alkyl carboxylic esters in the presence of aryl esters.
Regiospecific phenyl esterification to some organic acids catalyzed by combined Lewis acids
Roy,Mamun, A. H. Al
, p. 2975 - 2981 (2007/10/03)
A new and efficient method for the preparation of various phenyl esters has been achieved by a simple reaction of an acid with phenol in the presence of anhyd. ZnCl2 and a catalytic amount of AlCl3. This combined Lewis acid also catalyzes the selective phenyl esterification to different dioic acids and is very simple and high yielding. Copyright Taylor & Francis Group, LLC.
Formation of Dichloromethyl Phenyl Ethers as Major Products in Photo-Reimer-Tiemann Reaction without Base
Jimenez, M. Consuelo,Miranda, Miguel A.,Tormos, Rosa
, p. 5825 - 5830 (2007/10/02)
Photolysis of phenols 1a-d in chloroform or carbon tetrachloride afforded the corresponding di- or trichloromethyl phenyl ethers (2a-d or 6a-d, respectively).In chloroform, hydroxybenzaldehydes 4a-d or 5 and phenyl formates 3a-d were obtained as minor photoproducts.In carbon tetrachloride, traces of salicyloyl chloride (7), phenyl salicylate (8) and phenyl p-hydroxybenzoate (9) were detected starting from the parent phenol (1a).The obtained results agree with the involvement of an electron transfer mechanism.
