Deuteriochlorodiphenylmethane, also known as deuterated diphenylmethane, is a chemical compound that is structurally similar to diphenylmethane but contains deuterium atoms instead of regular hydrogen atoms. It is represented by the chemical formula C13D7ClH10. deuteriochlorodiphenylmethane is primarily used as a reference material in various analytical techniques, such as mass spectrometry and nuclear magnetic resonance (NMR) spectroscopy, due to its unique isotopic composition. The presence of deuterium atoms in the molecule allows for better resolution and differentiation of signals in these analytical methods, making it a valuable tool in the field of chemistry and research.

778-23-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 778-23-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,7 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 778-23:
(5*7)+(4*7)+(3*8)+(2*2)+(1*3)=94
94 % 10 = 4
So 778-23-4 is a valid CAS Registry Number.

Dilithium Diphenylmethanediide; Generation, Redox Relationship with Lithium Chlorodiphenylmethanide, Implication with Regard to Aggregation

Eikema Hommes, Nicolaas J. R. van,Bickelhaupt, Friedrich,Klumpp, Gerhard W.

, p. 438 - 440 (1991)

Dilithium diphenylmethanediide, Ph2CLi2, prepared by reaction of dichlorodiphenylmethane with lithium p,p'-di-tert-butylbiphenyl, reacts with organic halides and carbonyl compounds to give lithium chlorodiphenylmethanide, Ph2CLiCl, as a major product and is assumed to exist in two different states of aggregation.
