3-chloro-3-methyl-3H-diazirene is a chemical compound with the molecular formula C3H4ClN3. It is a halogenated derivative of 3-methyl-3H-diazirene, featuring a chlorine atom attached to the carbon atom in the 3-position. This molecule is characterized by its diazirene structure, which consists of a three-membered ring containing two nitrogen atoms and one carbon atom. The presence of the chlorine atom and the methyl group (a carbon atom bonded to three hydrogen atoms) on the same carbon atom in the 3-position imparts unique chemical properties to the molecule. 3-chloro-3-methyl-3H-diazirene is of interest in organic chemistry and may have potential applications in the synthesis of various pharmaceuticals and chemical compounds due to its reactive nature and the presence of a halogen atom, which can participate in various chemical reactions.

4222-21-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4222-21-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,2 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4222-21:
(6*4)+(5*2)+(4*2)+(3*2)+(2*2)+(1*1)=53
53 % 10 = 3
So 4222-21-3 is a valid CAS Registry Number.

Tracking "invisible" alkylchlorocarbenes by their σ → p absorptions: Dynamics and solvent interactions

Moss, Robert A.,Tian, Jingzhi,Sauers, Ronald R.,Krogh-Jespersen, Karsten

, p. 10019 - 10028 (2007)

Contrary to implications in the literature, the σ → p absorptions of alkylchlorocarbenes (RCCl) are readily acquired by laser flash photolysis with UV-vis detection in solution at ambient temperature. Examples include RCCl with R = methyl, benzyl, t-butyl, 1-adamantyl, and cyclopropyl. These absorptions permit direct monitoring of carbene reactions and the formation of carbene-solvent complexes. The kinetics of the reactions of "free" and complexed MeCCl and PhCH2CCl were directly followed with tetramethylethylene and 1-hexene. Particularly effective complexation was provided by anisole and 1,3-dimethoxybenzene, which modulated the rates of intermolecular carbene additions. Computational studies are presented, which aid in understanding the carbene absorption spectra and the nature of the solvent complexes.
