p,p'-Octylidenebisphenol, also known as 4,4'-(1-Methylethylidene)bisphenol or Bisphenol A, is an organic compound with the chemical formula C15H16O2. It is a white crystalline solid that is widely used in the production of polycarbonate plastics and epoxy resins. This chemical is known for its ability to mimic estrogen in the body, which has raised concerns about its potential health effects, particularly in relation to endocrine disruption. Bisphenol A is commonly found in everyday products such as food and beverage containers, dental sealants, and thermal paper receipts. Due to its potential health risks, many countries have restricted or banned its use in certain applications, especially those that come into direct contact with food or beverages.

1233-26-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1233-26-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,3 and 3 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1233-26:
(6*1)+(5*2)+(4*3)+(3*3)+(2*2)+(1*6)=47
47 % 10 = 7
So 1233-26-7 is a valid CAS Registry Number.

Metal cation-exchanged montmorillonite (Mn+-mont)-catalysed aromatic alkylation with aldehydes and ketones

Tateiwa, Jun-Ichi,Hayama, Ei,Nishimura, Takahiro,Uemura, Sakae

, p. 1923 - 1928 (2007/10/03)

The alkylation of aromatic compounds with aldehydes and ketones in the presence of a variety of metal cation-exchanged montmorillonites (Mn+-mont; Mn+ = Zr4+, Al3+, Fe3+, Zn2+, H+, Na+) has been investigated. Al3+- and Zr4+-Monts are revealed to be effective as catalysts, while no reaction takes place with Na+-mont. Al3+-Mont-catalysed alkylation of phenol with several aldehydes produces mainly or almost solely the corresponding gem-bis(hydroxyphenyl)alkanes (bisphenols) in good yields, while that with several ketones affords selectively the corresponding alkylphenols in moderate to good yields. The alkylation always occurs at the carbonyl carbon without any skeletal rearrangement and the kind of products depends much on the steric hindrance of an electrophilic intermediary carbocation. The alkylation of anisole, veratrole and p-cresol proceeds well, while that of toluene, benzene, chlorobenzene and nitrobenzene scarcely occurs.
