Chromatography Standards
Poly(ethylene glycol) for GPC 4,000, MilliporeSigma™ Supelco™
Poly(ethylene glycol) (PEG) is regarded as the gold standard for stealth polymers in polymer based drug delivery. PEGs and their anionic or non-ionic derivatives are widely used in cosmetic products.
Glycitein, ≥98.0% (HPLC), MilliporeSigma™ Supelco™
Glycitein is an isoflavone found in soy food products.
phyproof™ 4-Hydroxyisophthalic acid, ≥90% (HPLC), MilliporeSigma™ Supelco™
This substance is a primary reference substance with assigned absolute purity (considering chromatographic purity, water, residual solvents, inorganic impurities). The exact value can be found on the certificate. Produced by PhytoLab GmbH & Co. KG
Tetradecane, Analytical Standard, ≥99.5% (GC), MilliporeSigma™ Supelco™
Tetradecane is a hydrocarbon comprising of 14 carbon atoms and 30 hydrogen atoms. It can undergo combustion reaction to liberate carbon dioxide and water.
TraceCERT™ β-Endosulfan Certified Reference Material, MilliporeSigma™ Supelco™
This certified reference material (CRM) is produced and certified in accordance with ISO/IEC 17025 and ISO 17034. This CRM is traceable to primary material from an NMI, e.g. NIST or NMIJ.Certified content by quantitative NMR incl. uncertainty and expiry date are given on the certificate.
PESTANAL™ Flusilazole, MilliporeSigma™ Supelco™
Flusilazole is an organosilicon fungicide, which belongs to the class of sterol demethylation inhibitors. Its mode of action involves the inhibition of lanosterol 1,4-α-demethylation in fungal sterol biosynthesis.
Octanoic acid, ≥99.5% (GC), MilliporeSigma™ Supelco™
Octanoic acid is a medium chain saturated fatty acid (MCFA). It is a nutrient present in dairy products and specific oils like palm kernel and coconut oils.
