1,3-Benzenedicarbonyl diisothiocyanate, also known as terephthaloyl diisothiocyanate (TDI), is an organic compound with the chemical formula C8H4N2O2S2. It is a white crystalline solid that is widely used in the production of polyurethane foams, elastomers, and coatings. TDI is synthesized by reacting phosgene with isothiocyanic acid, resulting in a highly reactive compound that can form strong, flexible, and durable materials. Due to its reactivity, it is essential to handle TDI with proper safety precautions, as it can cause skin and respiratory irritation, and prolonged exposure may lead to more severe health issues.

Check Digit Verification of cas no

The CAS Registry Mumber 70112-91-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,1,1 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 70112-91:
(7*7)+(6*0)+(5*1)+(4*1)+(3*2)+(2*9)+(1*1)=83
83 % 10 = 3
So 70112-91-3 is a valid CAS Registry Number.

(Equation present) A series of symmetrical 1,3-bis thiourea 1a-e and 1,4-bis thiourea derivatives 2a-e have been successfully synthesized from the reactions of amines with 3-acetylbenzoyl isothiocyanate and 4-acetylbenzoyl isothiocyanate, respectively. All the synthesized compounds were characterized by FT-IR spectroscopy and 1H and 13C NMR spectroscopy. The compounds were screened for their antibacterial activity by turbidimetric method using gram-negative bacteria (E. coli ATCC 8739) using turbidimetric method. The newly synthesized bis-thiourea derivatives bearing aryl side chains showed good antibacterial activity against E. coli. The effect of the molecular structure of the synthesized compounds on the antibacterial activity is discussed. 2014 Copyright Taylor & Francis Group, LLC.

The present study includes the evaluation of antioxidant, cytotoxic, antiureas and some other enzymes like a-chymotrypsin, acetylcholinesterse, butyrylcholinesterase inhibition activity of some synthesized N3,N3'-bis(disubstituted)isophthalyl-bis(thioureas) and N3,N3,N3',N3'- tetrakis(disubstituted)isophthalyl-bis(thiourea) compounds with general formula [C6H4{CONHCSNR1R2}2], where R1 = H (L1-L5), C6H6(L6), and R2 = 4-C6H4COOH(L1), 3- NO2C6H4(L2), 2-NO2C6H4(L3), 4-NO2C6H4(L4), C5H4N(L5) and C6H11(L6) and their Cu(II) and Ni(II) complexes. The antioxidant inhibition was measured against standard butylated hydroxyl toluene for all the synthesized compounds. Thiourea used as standard against antiureas inhibition. The enzyme inhibition IC50 values were used to describe the results. The results of these studies also show that the metal (II) complexes have more potential activity against different enzymatic inhibitions as compared to uncomplexed ligands. The results reveal that synthesized thioureas and their metal (II) complexes can be used as potential inhibitors against some disease causing enzymes like ureas etc.

A series of some novel N3,N3'-bis(disubstituted) isophthalyl-bis(thioureas) compounds with general formula [C6H 4{CONHCSNHR}2], where R = 4-C6H 4COOH(L1), 3-NO2C6H 4(L2), 2- NO2C6H4(L 3), 4-CH3C6H4(L4), 2-CH3C6H4(L5), 3-CH 3C6H4(L6) and their Cu(II) and Ni(II) complexes have been synthesized. (L1-L6) have been prepared in good to excellent yields by reaction of isophthaloyl isothiocyanate with primary amines using dry acetone as solvent. The stoichiometric reaction between the metal (II) ion and synthesized ligands in molar ratio of M : L (1 : 1) resulted in the formation of the metal complexes of type [ML]2 (where M = Cu(II) and Ni(II). These compounds (L1-L6) and their metal (II) complexes have been characterized by elemental analyses, Infrared spectroscopy, 1H-NMR spectroscopy, magnetic moments, and electronic spectral measurements. These compounds (L1-L6) and their metal (II) complexes were also screened for their antibacterial activity against bacterial species, Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Shigella sonnei, Salmonella typhi and Pseudomonas aeroginosa. Some compounds showed potential activity against a number of bacterial strains. The results of these studies also show the metal (II) complexes to be having stronger antibacterial activityl against one or more species as compared to the uncomplexed ligands. It was concluded that these compounds may be the potential source of active antibacterial agents.
