21245-02-3 Usage

Description

2-Ethylhexyl 4-dimethylaminobenzoate, also known as Padimate O, is a tertiary amine derivative of p-aminobenzoic acid (PABA). It is a colorless to yellow liquid that is commonly used as a sunscreen agent in cosmetics and other sunscreen formulations due to its ability to absorb ultraviolet radiations.

Uses

Used in Cosmetics and Sunscreen Industry:
2-Ethylhexyl 4-dimethylaminobenzoate is used as an UV-B-absorbing agent for protecting the skin from harmful ultraviolet radiations. It is widely utilized in sunscreens, cosmetic creams, lotions, lipsticks, sun oils, moisturizers, and nail polish to provide sun protection and prevent skin damage caused by UV-B rays.
Used in Pharmaceutical Industry:
Although not explicitly mentioned in the provided materials, Padimate O may also be used in the pharmaceutical industry for the development of topical medications that require UV-B absorption properties, such as certain skin treatments or anti-inflammatory agents.

Check Digit Verification of cas no

The CAS Registry Mumber 21245-02-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,4 and 5 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 21245-02:
(7*2)+(6*1)+(5*2)+(4*4)+(3*5)+(2*0)+(1*2)=63
63 % 10 = 3
So 21245-02-3 is a valid CAS Registry Number.

Nucleophilic acyl substitutions of esters with protic nucleophiles mediated by amphoteric, oxotitanium, and vanadyl species

Chen, Chien-Tien,Kuo, Jen-Huang,Ku, Cheng-Hsiu,Weng, Shiue-Shien,Liu, Cheng-Yuan

, p. 1328 - 1339 (2007/10/03)

(Chemical Equation Presented) A diverse array of oxometallic species were examined as catalysts in nucleophilic acyl substitution (NAS) reactions of methyl (or ethyl) esters with protic nucleophiles. Among them, oxotitanium acetylacetonate (TiO(acac)2) and vanadyl chloride (VOCl 2-(THF)x) served as the most efficient and water-tolerant catalysts. Transesterifications of methyl and/or ethyl esters with functionalized (including acid- or base-sensitive) 1° and 2° alcohols can be carried out chemoselectively in refluxed toluene or xylene in a 1:1 substrate stoichiometry using 1 mol % catalyst loading. The resultant products were furnished in 85-100% yields by simple aqueous workup to remove water-soluble catalysts. The new NAS protocol is also amenable to amines and thiols in 74-91% yields, albeit with higher loading (2.5 equiv) of protic nucleophiles. Representative examples of commercial interests such as Padimate O and antioxidant additives for plastics were also examined to demonstrate their practical applications. A 1:1 adduct between TiO(acac)2 and a given 1-octadecanol was identified as (C18H37O) 2Ti(acac)2 and was responsible for its subsequent NAS of methyl esters.
