74886-37-6 Usage
General Description
1,1-bis(4-chlorophenyl)but-3-yn-1-ol is a chemical compound that belongs to the class of alkynols. It has a molecular formula C16H11Cl2O and a molecular weight of 297.16 g/mol. 1,1-bis(4-chlorophenyl)but-3-yn-1-ol is also known by its common name, dicofol, and is used as a pesticide to control a variety of insects and mites on agricultural crops like fruits, vegetables, and ornamental plants. However, it has been banned in several countries due to its potential to persist in the environment and impact human and environmental health. Dicofol is a white, waxy solid with a melting point of 79-81°C and is soluble in organic solvents like ethanol and acetone. It is important to handle and use this compound with caution due to its toxic properties.
Check Digit Verification of cas no
The CAS Registry Mumber 74886-37-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,8,8 and 6 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 74886-37:
(7*7)+(6*4)+(5*8)+(4*8)+(3*6)+(2*3)+(1*7)=176
176 % 10 = 6
So 74886-37-6 is a valid CAS Registry Number.

A novel and highly efficient synthetic approach to cyclopropanes was realized via 1,3-migration of acyloxy groups triggered by α-imino rhodium carbenes. Excellent chemoselectivity ensured broad compatibility of common functional groups. Merits such as readily available substrates, mild reaction conditions, and time-saving processes qualified this transformation as an attractive alternative strategy to synthesize multifunctionalized cyclopropanes. Primary investigations and discussion on the mechanism are presented.
