Phenol, 2,2'-(phenylmethylene)bis[5-methyl-, also known as 5,5'-Bis(5-methyl-2-benzoxazolyl)-2,2'-bithiophene or BBOT, is a white to yellowish powder that is soluble in organic solvents. It is a chemical compound primarily used as a fluorescent brightening agent in various industries.
Used in Textile Industry:
BBOT is used as a fluorescent brightening agent for enhancing the brightness and whiteness of textiles. It absorbs ultraviolet light and re-emits it in the visible spectrum, improving the appearance of fabrics.
Used in Plastics Industry:
In the plastics industry, BBOT is used as a stabilizer to prevent discoloration and degradation of plastic materials from exposure to light. This helps maintain the color and quality of plastic products over time.
Used in Paper Industry:
BBOT is also used in the paper industry as a fluorescent brightening agent to improve the brightness and whiteness of paper products. This enhances the visual appeal and quality of paper materials.
However, it is important to note that BBOT has been found to have potential harmful effects on human health and the environment. As a result, there has been increased scrutiny and regulation of its use in recent years.

32094-28-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 32094-28-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,0,9 and 4 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 32094-28:
(7*3)+(6*2)+(5*0)+(4*9)+(3*4)+(2*2)+(1*8)=93
93 % 10 = 3
So 32094-28-3 is a valid CAS Registry Number.

Access to Enantiopure Triarylmethanes and 1,1-Diarylalkanes by NHC-Catalyzed Acylative Desymmetrization

Lu, Shenci,Song, Xiaoxiao,Poh, Si Bei,Yang, Hui,Wong, Ming Wah,Zhao, Yu

, p. 2275 - 2281 (2017)

We present herein an unprecedented, efficient and enantioselective synthesis of triarylmethanes and 1,1-diarylalkanes through N-heterocyclic carbene-catalyzed acylative desymmetrization of bisphenols. This method utilizes readily available substrates, reagents and a simple procedure to deliver the valuable products in excellent enantiopurity. DFT calculations reveal that the selectivity is governed by the C?C bond cleavage step of the tetrahedral intermediate leading to the ester product. A transition state model featuring a combination of intramolecular hydrogen bond and steric effect is developed to explain the enantioselectivity.

-

, (2008/06/13)

The developer for a thermal recording material of the present invention comprises a condensed composition consisting of, of condensates represented by the formula (1): wherein R is a hydrogen atom, a hydroxyl group, a lower alkyl group having 1 to 5 carbon atoms, an alkoxyl group having 1 to 5 carbon atoms, an aryl group or an aralkyl group, R in the number of m may be the same or different and m is an integer of 0-3, X and Y are each a hydrogen atom, an alkyl group or an aryl group, provided that at least one of X an dY is an alkyl group or an aryl group, and n is an integer of 0-3, a condensate having two cores wherein n="0 or a condensed composition comprising a condensate having two cores wherein" n=0 as a main component, and at least one kind of condensate of the formula wherein n=1-3 (3-5 core condensate). The developer for thermal recording materials of the present invention is applied to a heat-coloring layer of thermal recording materials, along with a basic dye (preferably further with a sensitizer). According to the present invention, a developer for thermal recording materials, which is capable of realizing a thermal recording material capable of affording high colored image density and superior in preservation stability (particularly heat resistance and moisture resistance) of recorded images and non-image areas, while satisfying recent requirements for high sensitivity, can be obtained.
