5334-11-2 Usage
General Description
Triphenylethenyl benzoate, also known as Tinopal CBS-X, is a fluorescent whitening agent commonly used in the textile industry to enhance the brightness and whiteness of fabrics. It works by absorbing ultraviolet light and emitting blue light, which counteracts the yellowish tinge that can develop in textiles over time. Additionally, it is also used in the manufacture of plastics, coatings, and paper. Triphenylethenyl benzoate is considered safe for use in these applications and has low toxicity. However, it is important to handle and store this chemical properly to avoid any potential risks associated with its use.
Check Digit Verification of cas no
The CAS Registry Mumber 5334-11-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,3 and 4 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5334-11:
(6*5)+(5*3)+(4*3)+(3*4)+(2*1)+(1*1)=72
72 % 10 = 2
So 5334-11-2 is a valid CAS Registry Number.

REACTION OF DILITHIUM BENZOPHENONE, DILITHIUM 9-FLUORENONE AND THE LITHIUM SALT OF BENZOPHENONE KETYL WITH CHLORIDES AND ANHYDRIDES OF CARBOXYLIC ACIDS
Honzl, J.,Metalova, M.
, p. 297 - 306 (2007/10/02)
The reaction of dilithium benzophenone and the lithium salt of benzophenone ketyl with anhydrides and chlorides of benzoic and acetic acid and the reaction of dilithium 9-fluorenone with acetic anhydride were investigated.In addition to the expected products Ar2C(COR)OCOR, products of the type Ar2C=CR(OCOR) were also obtained, and in the case of reactions with acetyl chloride and acetic anhydride, products of the type Ar2CH(OCOR).ESR studies showed that ketyl is formed in the reaction of dilithium benzophenone with acetic anhydride, and the ClDNP method revealed thatbenzhydryl acetate is formed, at least in part, by hydrogen transfer to a free radical produced by O-acetylation of the ketyl.The results suggest a competition between addition and electron transfer reactions.
