Crystal violet bromide, also known as gentian violet or methylrosaniline chloride, is a chemical compound with the formula C25H30BrN3. It is a synthetic, basic dye that exhibits a deep violet color. Crystal violet bromide is widely used as a histological stain for the detection and visualization of microorganisms, particularly in the Gram staining technique. It is also employed in the textile industry for dyeing fabrics and in the pharmaceutical industry for the treatment of certain fungal infections. The compound is known for its antimicrobial properties, which are attributed to its ability to bind to bacterial cell walls and disrupt their function. However, due to its potential toxicity and mutagenicity, its use in some applications has been restricted or replaced with safer alternatives.

Check Digit Verification of cas no

The CAS Registry Mumber 3571-43-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,7 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3571-43:
(6*3)+(5*5)+(4*7)+(3*1)+(2*4)+(1*3)=85
85 % 10 = 5
So 3571-43-5 is a valid CAS Registry Number.

Chiral titanium(IV) and vanadium(V) salen complexes as catalysts for carbon dioxide and epoxide coupling reactions

Kuznetsova, Svetlana A.,Gorodishch, Ilia V.,Gak, Alexander S.,Zherebtsova, Valeria V.,Gerasimov, Igor S.,Medvedev, Michael G.,Kitaeva, Dinara Kh.,Khakina, Ekaterina A.,North, Michael,Belokon, Yuri N.

, (2021)

Chiral titanium(IV) and vanadium(V) salen complexes were found to catalyse the synthesis of cyclic carbonates from carbon dioxide and epoxides. Reactions could be conducted at room temperature and 50 bar pressure of carbon dioxide or at 100 °C and atmospheric pressure with catalyst concentrations as low as 0.1 mol% and co-catalyst (tetrabutylammonium bromide) concentrations as low as 0.5 mol%. The cyclic carbonates formed were racemic and a mechanism is proposed which relies on Lewis base catalysis to activate the carbon dioxide rather than Lewis acid catalysed activation of the epoxide as more commonly proposed for catalysis by metal complexes.

Reaction of N,N-dimethylaniline (1) with tetrahalomethanes such as tetrabromomethane and tetrachloromethane in acetonitrile was found to give 4,4′-methylenebis(N,N-dimethylaniline) (2) in considerable yield. The reaction is considered to be initiated by t

Photochemical Reactions of Bromoanthracenes with N,N-Dimethylaniline in Solution

Fulara, Jan,Latowski, Tadeusz

, p. 846 - 851 (2007/10/02)

Major products of the photolysis of 9-bromoanthracene and 9,10-dibromoanthracene in benzene and acetonitrile as well as photochemical reaction products of the two bromoanthracenes with N,N-dimethylaniline in these solvents have been isolated and identified.The mechanisms of partial reactions are discussed and attention is paid to the medium effect on the photochemical transformations. - Keywords: Photochemical Reactions, Bromoanthracenes
