108059-85-4 Usage

General Description

2-(2-ethylbenzoyl)benzoic acid, also known as EBA, is an aromatic compound with the molecular formula C16H14O3. It is a derivative of benzoic acid and is commonly used in the production of sunscreens and other cosmetic products due to its UV-absorbing properties. EBA is a white, crystalline powder that is insoluble in water but soluble in organic solvents. It is also used in the synthesis of various pharmaceutical compounds and as a reagent in organic chemistry reactions. EBA is considered to be relatively safe for use in cosmetic and pharmaceutical products, with low toxicity and minimal potential for skin irritation or sensitization.

Check Digit Verification of cas no

The CAS Registry Mumber 108059-85-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,0,5 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 108059-85:
(8*1)+(7*0)+(6*8)+(5*0)+(4*5)+(3*9)+(2*8)+(1*5)=124
124 % 10 = 4
So 108059-85-4 is a valid CAS Registry Number.

Comparison of photoenolization and alcohol release from alkyl-substituted benzoyl benzoic esters

Muthukrishnan, Sivaramakrishnan,Pace, Tamara C.S.,Li, Qian,Seok, Brian,De Jong, Gerdien,Bohne, Cornelia,Gudmundsdottir, Anna D.

experimental part, p. 331 - 338 (2011/06/22)

Photolysis of 1B in argon-saturated solutions yields 4B and releases methanol. Laser flash photolysis of 1B shows formation of biradical 2B, which has a lifetime of ~50 ns and a max at 330 nm. Biradical 2B undergoes an intersystem crossing to form photoenols E-3B and Z-3B with a max at 390 nm. Laser flash photolysis shows that the lifetimes of E-3B and Z-3B are affected by the solvent. Density functional theory calculations demonstrate that the transition-state barrier for a 1,5-H atom shift from Z-3B to regenerate 1B is affected by the ortho-alkyl substituents, whereas the stereoelectronics of the alkyl substituent affect the transition-state barrier of E-3B as it undergoes electrocyclic ring closure to form 4B. The photoreactivity of 1B was compared with its analogous methyl and isopropyl derivatives 1A and 1C, respectively,to better estimate the effect of the alkyl substituent on reactivity.

Dibenzocyclooctene-, Dibenzochalcocine-, and Diarenochalconinediones

Hellwinkel, Dieter,Bohnet, Siegbert

, p. 1151 - 1174 (2007/10/02)

2,2'-Oxybis-, -thiobis-, and -methylenebisbenzoic esters 2a-c react with methyllithium in ether to give low yields of 5H-dibenzochalcocine-5,7(6H)-diones 6a, 7a, and dibenzocyclooctene-5,7(6H,12H)-dione (8), respectively.Very good yields of such heterocycles with oxygen (6a-h, 37), sulfur (7a-h, 38) and selenium (36) as key atom are obtained when diaryl ethers (21, 22, 25), -sulfides (27, 29, 30), and -selenides (33) that contain 2'-acetyl- (or -propionyl-) and 2-methoxycarbonyl groups are treated with sodium hydride in boiling toluene.Analogously are prepared the dibenzoxonine-11,13(6H,12H)diones 62a-c and 7H-benzonaphthothionine-7,9-(8H)-dione (65) which are expanded by one ring member.In the analogous reaction of a corresponding benzophenone derivative 35, spiro-3(2H),3'-dione (41) is formed in a tandem reaction. - Under phase transfer conditions the dibenzochalcocinediones 6, 7, 36 and also the corresponding nitrogen cycles 5 react to give mixtures of C- (42-45) and O-alkyl derivatives (46-49).Methyllithium and diisobutylaluminium hydride provide the carbinols 50-54.With bromine and SO2Cl2, respectively, the methylene group is mono- or dihalogenated to the products 56, 57; defined nitration was only possible for the oxacycle 6a.
