Description générale

Glacial acetic acid is the trivial name used to describe pure acetic acid in an anhydrous state. It is a clear and hygroscopic weak acid, typically available in concentrations ranging from 99.5% to 100%. The name "glacial" refers to the ice-like crystals that form at a temperature slightly below room temperature (16.6°C or 61.9°F), like the German term "Eisessig" (ice-vinegar). Despite being classified as a weak acid, glacial acetic acid is a corrosive poison that can cause harm or even be fatal when in contact with human tissue. Improper storage and handling of glacial acetic acid can pose inherent risks and may lead to patient injuries if not appropriately diluted. Acetic acid/acetate is a common counter ion in peptide preparations.
Glacial acetic acid USP reference standard is provided as delivered and specified by the issuing Pharmacopoeia. All information provided in support of this product, including SDS and any product information leaflets have been developed and issued under the Authority of the issuing Pharmacopoeia. For further information and support please go to the website of the issuing Pharmacopoeia.

Application

Glacial acetic acid USP reference standard for use in specified quality tests and assays. It is also used to prepare standard solution by using liquid chromatography coupled to a UV detector according to the general chapter of United States Pharmacopeia (USP). Based directly on official monographs published in the USP-NF, these highly characterized physical specimens are used in testing by pharmaceutical and related industries to help ensure the identity, strength, quality, and purity of peptide-based medicines.

Further information is available in the general chapter, 503- ACETIC ACID IN PEPTIDES, USP43-NF38 - 6741 of the USP (United States Pharmacopeia).

GC Analysis of Free Fatty Acids in Parmesan Cheese using Nukol™ after SPME using 65 μm Carbowax/DVB Fiber

In this study, SPME was used for the analysis of free fatty acids in Parmesan cheese using a 65 μm Carbowax/divinylbenzene (DVB) SPME fiber. Headspace extraction of the cheese sample was conducted at 65 °C for 15 minutes and analyzed by GC with FID detection. SPME is ideal for analyzing the volatiles associated with solid food samples. The phase chemistry of the Nukol GC column provides excellent peak shape of acidic compounds.
