(β-Hydroxyethyl)diphenylarsan, also known as 2-(Diphenylarsanyl)ethanol, is an organoarsenic compound characterized by the presence of an arsenic atom bonded to a hydroxyethyl group and two phenyl rings. This chemical has the molecular formula C14H15AsO and a molecular weight of 262.15 g/mol. It is a colorless to pale yellow liquid with a density of 1.22 g/cm3 and a melting point of 40-42°C. The compound is sensitive to light and heat, and it is soluble in organic solvents such as ethanol, acetone, and dichloromethane. (β-Hydroxyethyl)diphenylarsan has potential applications in the synthesis of pharmaceuticals and agrochemicals, as well as in materials science for the development of new compounds with unique properties. However, due to its arsenic content, it is essential to handle (β-Hydroxyethyl)diphenylarsan with care, as arsenic and its compounds are known to be toxic and can pose health risks if not properly managed.
The CAS Registry Mumber 4645-25-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,4 and 5 respectively; the second part has 2 digits, 2 and 5 respectively. Calculate Digit Verification of CAS Registry Number 4645-25: (6*4)+(5*6)+(4*4)+(3*5)+(2*2)+(1*5)=94 94 % 10 = 4 So 4645-25-4 is a valid CAS Registry Number.
