Ethanol
Ethanol is a volatile, flammable, simple, organic alcohol. Available in various reagent grades, it has applications as a lab/medicinal solvent, an antiseptic, a fuel source/additive, a precursor to organic compounds, etc.
Denatured alcohol (CAS 64-17-5), also known as denatured ethanol or industrial methylated spirit (IMS), is ethanol (ethyl alcohol) to which has been added small known quantities of other substances, so as to ‘denature’ or adulterate it in a controlled manner.
What Additives are Used in Denatured Alcohol?
Often, the additive is methanol (at 5 to 10%), but isopropanol (IPA), methyl ethyl ketone (MEK), acetone or methyl isobutyl ketone (typically all at 1%) may be used. Denatonium can be added for a bitter taste, colored dyes such as methyl violet for visual identification, or a combination may also be used. The purpose of these additives is to create ethanol that is not suitable for human consumption.
The primary purpose of denaturation is to render the ethanol unfit, unpalatable, and unsafe for recreational human consumption, or unsuitable for any other unauthorized purpose. Denaturation usually makes the product exempt from duty payable and other taxes, making it cheaper to purchase.
How Is Denatured Alcohol Used?
Denatured alcohol is used commercially and in industry:
• As a general-purpose solvent, especially for removal of adhesives, waxes, and paint
• For cleaning and degreasing apparatus and equipment
• As a fuel for burners and stoves
• As a surface disinfectant or sterilizer for use in cleanrooms, laboratories, and clinical environments, presented as a liquid, spray, gel, or pre-moistened wiper
• As a preservative and antibacterial agent in cosmetics
Denatured alcohol with added methanol is acutely toxic. It is flammable at room temperature and storage in a secure location is recommended. Due attention should also be given to all other appropriate precautions necessary for handling these chemicals.

Innovative Research Inc Ms IgG Frctn Pur 1gm
Mouse IgG Fractionated Purified 1gm - Mouse IgG Fractionated Purified from Innovative Research has been purified from mouse serum by fractionation. This is a frozen liquid buffered in 10mM sodium phosphate, 150mM sodium chloride pH 7.2 and a purity of greater than 97% as determined by SDS-PAGE analysis. This product is useful as a co-precipitant in radioimmunoassay methods that use polyethylene glycol or ammonium sulfate precipitaiton, and as a protein stabilizer blocker for immunoassays. This is also useful as an IgG control for biochemical analytical testing. Immunoglobulin G (IgG) is an antibody that plays a role in controlling infection, neutralizing toxins, activating the classical pathway of the complement system, and more. Each individual IgG contains two identical antigen binding sites. There are four subclasses of IgG (IgG1, IgG2, IgG3, and IgG4) that have different (and sometimes opposing) properties.

200 proof, HPLC/spectrophotometric grade, Linear Formula: CH3CH2OH, Molecular Weight: 46.07, Synonym: Ethanol, absolute alcohol, non-denatured ethanol. BP: 78.3 °C, MP: -114 °C. Pure ethyl alcohol is a non-denatured 200proof ethanol. Ethanol, a primary alcohol, is an important raw material for the synthesis of various compounds. It can be synthesized either from molasses by fermentation or by hydration of ethylene. It acts as a hydrogen source and reaction medium during the transfer hydrogenation of carbonyl compounds in the presence of sodium hydroxide. The impact of ethanol/water fumigation on the performance of diesel engines has been studied. Spectrophotometric grade solvent is of high purity with low UV absorption.
