Benzoic acid, 4,4'-oxybis-, diphenyl ester, also known as Bisphenol A diphenyl phosphate (BPA-DPhP) or 4,4'-(1-Methylethylidene)bisphenol diphenyl phosphate, is a flame retardant chemical compound. It is a white crystalline solid with a molecular formula of C27H22O4P and a molecular weight of 438.44 g/mol. BPA-DPhP is primarily used as a plasticizer and flame retardant in various applications, including polyurethane foams, epoxy resins, and other polymers. It is known for its high thermal stability, low volatility, and excellent flame retardant properties. However, concerns have been raised about its potential health and environmental impacts, as it is structurally similar to Bisphenol A (BPA), a known endocrine disruptor. As a result, its use has been restricted or banned in certain products and regions.

2187-85-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2187-85-1 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 7 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2187-85:
(6*2)+(5*1)+(4*8)+(3*7)+(2*8)+(1*5)=91
91 % 10 = 1
So 2187-85-1 is a valid CAS Registry Number.
