Phenol, 4,4'-methylenebis[2-chloro-], also known as Bisphenol A (BPA), is an organic compound with the chemical formula C15H16Cl2O2. It is a white crystalline solid that is primarily used in the production of polycarbonate plastics and epoxy resins. BPA is a key component in the manufacturing of various consumer products, such as food and beverage containers, dental sealants, and thermal paper receipts. However, it has been a subject of concern due to its potential endocrine-disrupting properties and health risks associated with long-term exposure, leading to restrictions and bans in certain applications.

2787-77-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2787-77-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,8 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2787-77:
(6*2)+(5*7)+(4*8)+(3*7)+(2*7)+(1*7)=121
121 % 10 = 1
So 2787-77-1 is a valid CAS Registry Number.

One-step novel synthesis of methylene bisphenols and methylene bisnaphthols using Lewis acid mediated rearrangement

Kumar, Sandeep,Mehta, Shilpika Bali

, (2021/12/20)

Mono- and di-substituted isomeric methylene bisphenols and methylene bisnaphthols have been synthesized by rearrangement of the corresponding O-methoxyacetyl derivatives of phenols and naphthols, respectively, in presence of aluminium chloride under dry conditions. The chemistry observed is different from the usual Fries rearrangement reaction and involves an intermolecular rearrangement. The reactions reported here also reflect the influence of substituents present in the substrate as is supported by the substitution of the bridging methylene at a position meta to the phenolic hydroxyl in some of the minor products formed along-side the majorly formed ortho substituted products.
