The odor and taste threshold for 1-octanol was reported at about 24 ppm.
The primary aliphatic alcohols undergo two general reactions in vivo, namely oxidation to carboxylic acids and direct conjugation with glucuronic acid. The first reaction proceeds with the intermediate formation of an aldehyde, and the carboxylic acid from the aldehyde may be either oxidized completely to carbon dioxide or excreted as such or combined with glucuronic acid as an ester glucuronide. The extent to which an alcohol undergoes the second reaction, i.e. direct conjugation to an ether glucuronide, appears to depend upon the speed of the first reaction. Alcohols which are rapidly oxidized form very little ether glucuronide unless given in high doses.
The urinary metabolites of n-octane in Fischer 344 rats given the hydrocarbon by gavage included 2-octanol, 3-octanol, 5-oxohexanoic acid, and 6-oxoheptanoic acid. The sex of the animals influenced the relative amounts of metabolites formed. Analyses were performed by gas-liquid chromatography (GC) and gas-liquid chromatography/mass spectrometry (GC/MS). This is the first reported finding of keto acids in hydrocarbon oxidative metabolism. No kidney damage was found as a result of n-octane dosing although the 2,2,4-trimethylpentane (iso-octane) isomer does cause kidney lesions in male rats. /n-Octane/
IDENTIFICATION AND USE: 1-Octanol is a colorless liquid used in the determination of partition coefficients, perfumery, cosmetics, organic synthesis, solvent manufacture of high-boiling esters, antifoaming agent, and as a flavoring agent. 1-octanol is registered for pesticide use in the USA but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses. It has been used as experimental medication to treat tremor in patients. HUMAN EXPOSURE AND TOXICITY: In a human patch test, 1-octanol in 2% petrolatum was neither a skin irritant nor a skin sensitizer. Octanol has caused transient injury of corneal epithelium, with recovery in 48 hr. Common signs of exposure to 1-octanol are CNS: headache, muscle weakness, giddiness, ataxia, confusion, delirium, coma. Gastrointestinal: nausea, vomiting, diarrhea (odor of the alcohol in excreta). Irritation of skin, eyes, throat from vapor or liquid with cough and dyspnea. The annoying odor of 1-octanol may mask sensory irritation and prevent subjects with enhanced chemical sensitivity from concentrating on performance in a demanding task. ANIMAL STUDIES: 1-Octanol was slightly irritating to the skin of rabbits and is considered an eye irritant using the EU criteria. n-Octanol (0.55 g/kg) produced the largest decrease in body temperature. No evidence of tumors in the lung adenoma study in which mice were injected intraperitoneally with 100 and 500 mg/kg 1-octanol three times a week for 8 weeks. Studies indicate that T-type calcium channels (T-channels) in the thalamus are cellular targets for general anesthetics. The study recorded T-currents and underlying low-threshold calcium spikes from neurons of nucleus reticularis thalami (nRT) in brain slices from young rats and investigated the mechanisms of their modulation by an anesthetic alcohol, 1-octanol. 1-Octanol inhibited native T-currents at subanesthetic concentrations with an IC(50) of approximately 4 uM. Inhibition of both native and recombinant T-currents was accompanied by a hyperpolarizing shift in steady-state inactivation, indicating that 1-octanol stabilized inactive states of the channel. In developmental studies in rats no treatment-related effects were observed in pregnant females, including frequency of resorptions, fetal weights, or skeletal/visceral malformations. 1-Octanol was negative in an Ames Salmonella assay with strains Ta 98, TA 100, TA 1535, TA 1537, and TA 1538 at concentrations ranging from 4 to 2500 ug/plate with and without metabolic activation.

Ni-Catalyzed Carboxylation of Unactivated Primary Alkyl Bromides and Sulfonates with CO2
摘要:
A Ni-catalyzed carboxylation of unactivated primary alkyl bromides and sulfonates with CO2 at atmospheric pressure is described. The method is characterized by its mild conditions and remarkably wide scope without the need for air- or moisture-sensitive reagents, which make it a user-friendly and operationally simple protocol en route to carboxylic acids.
