16069-32-2 Usage
General Description
Biphenyl-2,4-ylenediamine, also known as 2,4-diaminodiphenylmethane, is an organic compound that is commonly used as a curing agent in the production of polyurethanes and epoxy resins. It is a white to pale yellow solid with a slight odor and is soluble in organic solvents. It is a versatile chemical that is also used in the manufacturing of dyes, hair dyes, and rubber chemicals. It is considered to be a skin sensitizer and can cause irritation upon contact with skin and eyes, and ingestion or inhalation of the compound can be toxic. It is important to handle and store biphenyl-2,4-ylenediamine with care and follow proper safety measures when working with this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 16069-32-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,0,6 and 9 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 16069-32:
(7*1)+(6*6)+(5*0)+(4*6)+(3*9)+(2*3)+(1*2)=102
102 % 10 = 2
So 16069-32-2 is a valid CAS Registry Number.

The arylation of aromatic diamines with arylhydrazine hydrochlorides was achieved in reasonable yields. This new and simple reaction occurred at room temperature in air using an inexpensive base. This transformation seems to proceed via a homolytic aromatic substitution (HAS) mechanism. The synthesized aromatic diamines are used as raw materials for polyimides, including important aerospace materials, for example, Kapton
