N,N'-Propanediylidenedianiline, also known as 4,4'-(1-methylethylidene)bisbenzenamine or 4,4'-isopropylidene-bis-phenylamine, is an organic compound with the chemical formula C15H18N2. It is a white crystalline solid that is soluble in organic solvents and has a molecular weight of 230.32 g/mol. N,N'-propanediylidenedianiline is primarily used as a monomer in the production of polyamides, specifically in the synthesis of nylon-6T, a high-performance polymer known for its heat resistance and mechanical strength. N,N'-Propanediylidenedianiline is also used as a curing agent for epoxy resins, enhancing their adhesive and mechanical properties. Due to its reactivity and potential health risks, it is important to handle this chemical with care, following proper safety protocols.

5652-79-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5652-79-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,5 and 2 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5652-79:
(6*5)+(5*6)+(4*5)+(3*2)+(2*7)+(1*9)=109
109 % 10 = 9
So 5652-79-9 is a valid CAS Registry Number.

Synthesis and Photophysical Properties of λ5-Phosphinines as a Tunable Fluorophore

Hashimoto, Naoki,Umano, Rika,Ochi, Yusuke,Shimahara, Kiyoka,Nakamura, Jun,Mori, Shigeki,Ohta, Hidetoshi,Watanabe, Yutaka,Hayashi, Minoru

, p. 2046 - 2049 (2018)

A practical synthesis of a variety of λ5-phosphinines, which show distinct fluorescence both in solution and solid state, is described. Both C4-selective electrophilic substitutions and the following conversions realized an easy preparation of a wide range of derivatives having several substituents for electronic modification, which provides the potential for fine-tuning of the photophysical properties.
