Method for the synthesis of N-alkyl-O-alkyl carbamates
(Royal Society of Chemistry, 2014-02)
Primary and secondary carbamates were prepared from primary, secondary and neo-pentyl alcohols, and carbonyl-di-imidazole (CDI), using a new three step method. Non-acidic alcohols reacted with CDI affording carbamoyl-imidazoles ...
Ethyl carbamate kinetics in double distillation of sugar cane spirit
(INST BREWINGLONDON, 2012)
The aim of this study was to verify the effect of a double distillation on the reduction of the ethyl carbamate content in sugar cane spirit. Ethyl carbamate is a potentially carcinogenic compound normally present at ...
Detection of carbamate pesticides in vegetable samples using cholinesterase-based biosensors
(Wiley-Blackwell, 1997-10-01)
Biosensors for determination of carbamates in vegetables based on five different cholinesterases as biorecognition elements and a screen-printed electrode system as an amperometric transducer were developed. Measurements ...
Detection of carbamate pesticides in vegetable samples using cholinesterase-based biosensors
(Wiley-Blackwell, 1997-10-01)
Biosensors for determination of carbamates in vegetables based on five different cholinesterases as biorecognition elements and a screen-printed electrode system as an amperometric transducer were developed. Measurements ...
Determination of carbamate insecticides in apples, pears, and lettuce by LC with UV detector
(Aoac International, 1997-11-01)
A simple and rapid method was developed for determination of 8 carbamate insecticides and 10 of their metabolites in apples, pears, and lettuce by liquid chromatography with UV diode array detector. With this method no ...
Evaluation of the effect of ammonium carbamate on the stability of proteins
(WILEY-BLACKWELL, 2010)
BACKGROUND: The use of the volatile salt ammonium carbamate in protein downstream processing has recently been proposed. The main advantage of using volatile salts is that they can be removed from precipitates and liquid ...
Electrochemical detection of carbamate pesticides in fruit and vegetables with a biosensor based on acetylcholinesterase immobilised on a composite of polyaniline-carbon nanotubes
(ELSEVIER SCI LTDOXFORD, 2012)
A sensitive electrochemical acetylcholinesterase (AChE) biosensor was successfully developed on polyaniline (PANI) and multi-walled carbon nanotubes (MWCNTs) core-shell modified glassy carbon electrode (GC), and used to ...
Detection of carbamate pesticides in vegetable samples using cholinesterase-based biosensors
(Wiley-Blackwell, 2014)
Determination of carbamate residues in crop samples by cholinesterase-based biosensors and chromatographic techniques
(Elsevier B.V., 1998-04-24)
An amperometric biosensor based on cholinesterase (ChE) has been used for the determination of selected carbamate insecticides in vegetable samples. The linear range of the biosensor for the N-methylcarbamates (aldicarb, ...
Comparative study of hydrophobicity parameters of novel 5′-carbamates of zidovudine
(Taylor & Francis, 2005-12)
The lipophilic character of a series of 5′-carbamates of zidovudina has been studied. The lipophilicity was measured by means of reversed-phase thin layer chromatography (RP-TLC) and reversed-phase high performance liquid ...
