5045-40-9 Usage
General Description
3,3'-[(2-methyl-1,3-phenylene)diimino]bis[4,5,6,7-tetrachloro-1H-isoindol-1-one], also known as Pigment Green 36, is a synthetic organic compound commonly used as a pigment in various applications. It is a green powder with high opacity and good lightfastness, making it suitable for use in plastics, coatings, and printing inks. This chemical is derived from isoindoline and has a complex molecular structure consisting of two imine groups and multiple chlorine atoms. It is classified as a high-hiding pigment, meaning it provides excellent coverage and color strength. However, Pigment Green 36 has raised concerns about its potential environmental and health impacts, particularly due to its chlorine content. As a result, there has been ongoing research and regulation to ensure its safe use and disposal.
Check Digit Verification of cas no
The CAS Registry Mumber 5045-40-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,4 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5045-40:
(6*5)+(5*0)+(4*4)+(3*5)+(2*4)+(1*0)=69
69 % 10 = 9
So 5045-40-9 is a valid CAS Registry Number.

Page/Page column 22, (2010/02/14)
The present invention relates to advantageous processes for the manufacture of organic pigments and their precursors. The invention particularly relates to reactions carried out in an "All In One Reactor" (Draiswerke GmbH, Germany), a kneader like the TurbuKneader of the same company, a paddle dryer like the Turbudry of the same company or a related system and thereby submitting the reaction mixtures to enhanced driving power as expressed by a Froude number>1, the reaction mixture being caused to react in high concentrations at elevated temperature.
