2-Phenoxymethyl-2-methyl-propan-1,3-diyl-bis-toluen-4-sulfonat, also known as bisphenol A bis(toluene-4-sulfonate), is a complex organic compound that is derived from bisphenol A (BPA). 2-Phenoxymethyl-2-methyl-propan-1,3-diyl-bis- is characterized by its molecular structure, which includes a central propane-1,3-diyl group (a three-carbon chain) with two methyl groups attached to the central carbon, and two phenoxymethyl groups (each consisting of a benzene ring attached to a methyl group). The toluene-4-sulfonate groups are attached to the phenoxymethyl groups, providing the compound with its characteristic properties. This chemical is used in various applications, including as a precursor in the synthesis of polymers and as a stabilizer in certain industrial processes. It is important to note that bisphenol A and its derivatives have been subjects of concern due to potential health and environmental impacts, and as such, their use is regulated in some regions.
The CAS Registry Mumber 2180-22-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,8 and 0 respectively; the second part has 2 digits, 2 and 2 respectively. Calculate Digit Verification of CAS Registry Number 2180-22: (6*2)+(5*1)+(4*8)+(3*0)+(2*2)+(1*2)=55 55 % 10 = 5 So 2180-22-5 is a valid CAS Registry Number.
