Erratum to “Genotoxic effects of methyl isothiocyanate”

Mutation Research/Genetic Toxicology and Environmental Mutagenesis, 2001
Fig. 2. This figure shows induction of cytotoxicity ( ) and micronuclei ( ) in human derived HepG2 cells by MITC. The cells were exposed tovarious concentrations of the test chemical for 1h. The MN frequency was determined in binucleated cells (BNC) as described in the materialsand methods.

Infrared and Raman Spectra of Methyl Thiocyanate and Methyl Isothiocyanate

Zeitschrift für Elektrochemie, Berichte der Bunsengesellschaft für physikalische Chemie, 1960
AbstractInfrared spectra are reported for CH3SCN and CH3NCS from 170–3100 cm−1 for both liquid and vapor states. The Raman spectrum of CH3NCS has been re‐determined. A vibrational assignment is suggested for each molecule which is complete except for the methyl torsional frequencies.A useful qualitative means of distinguishing organic thiocyanates from

Accelerated Degradation of Methyl Isothiocyanate in Soil

Water, Air, and Soil Pollution, 2003
Methyl isothiocyanate (MITC, CH3NCS) is the primary breakdown product of metam-sodium, and a potential replacement fumigant pesticide for methyl bromide. Methyl isothiocyanate is toxic and has a high potential for volatilization, therefore, minimizing its atmospheric emission is of the utmost importance.

Reactions of alkene epoxides with methyl isothiocyanate

Bulletin of the Academy of Sciences, USSR Division of Chemical Science, 1964
1. In conjunction with triethylamine or pyridine alkene epoxides serve as catalysts for the trimerization of methyl isothiocyanate. 2. Methyl isothiocyanate trimer readily reacts with alkene epoxides in presence of TEAB with formation of the previously undescribed spiro compounds (I), (IV), (V), and (VI).

Reversible Insertion of Methyl Isothiocyanate into Copper(I) Aryloxides

Inorganic Chemistry, 1996
MeNCS undergoes insertion into the copper(I)-aryloxide bond to form [N-methylimino(aryloxy)methanethiolato]copper(I) complexes. This insertion occurs in the absence of ancillary ligands unlike the analogous insertion of PhNCS. The reaction with 4-methylphenoxide results in the formation of hexakis[[N-methylimino(4-methylphenoxy)methanethiolato]copper(I)

Conversion of metham‐sodium to methyl isothiocyanate and basic data on the behaviour of methyl isothiocyanate in soil

Pesticide Science, 1974
AbstractData were collected that are needed to simulate soil fumigation with metham‐sodium with computation models. The rate of conversion of metham‐sodium into methyl isothiocyanate was dependent on temperature and soil type, and conversion was usually completed within a few hours.

Reaction of ethylene oxide with methyl isothiocyanate

Bulletin of the Academy of Sciences, USSR Division of Chemical Science, 1964
When ethylene oxide reacts with methyl isothiocyanate in the presence of tetraethylammonium bromide, basically a compound of the spiran type (I) is obtained; thermal decomposition of this compound results in the formation of the trimethyl ester of dithioisocyanuric acid and ethylene sulfide.

Human chemosensory perception of methyl isothiocyanate: Chemesthesis and odor

Regulatory Toxicology and Pharmacology, 2010
An unpublished laboratory study by Russell and Rush (1996) showed that human subjects sense the presence of methyl isothiocyanate (MITC) via the eyes at concentrations as low as hundreds of ppb in air, with dependence upon duration of exposure. The longer the stimulation, the lower the concentrations sensed.

The microwave spectrum of methyl isothiocyanate

Journal of Molecular Spectroscopy, 1986
Abstract The microwave spectrum of methyl isothiocyanate, CH 3 NCS, has been measured in the range from 5 to 26 GHz. Almost 300 lines have been assigned to the a -type J + 1 ← J rotational transitions ( J = 0 to 4) arising from molecules in the ground state and excited torsional and CNC bending states.
