Chromatography Standards
Violaxanthin, ≥95.0% (HPLC), MilliporeSigma™ Supelco™
Violaxanthins are natural pigmented constituents or carotenoids present in most fruits and vegetables.
β-Alanine, ≥98.0% (HPLC), MilliporeSigma™ Supelco™
β-Alanine is a rate-limiting precursor of carnosine, a cytoplasmic dipeptide which is present in human skeletal muscles in high concentrations.
Methyl stearate, ≥99.5% (GC), MilliporeSigma™ Supelco™
Methyl stearate is a solid, saturated fatty ester, which can be prepared from methyl oleate via catalytic hydrogenation.
Estrone Pharmaceutical Secondary Standard, MilliporeSigma™ Supelco™
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.Estrone is a degradation product of the endogenous estrogen steroid, estradiol.
Methyl palmitate, ≥99.0% (GC), MilliporeSigma™ Supelco™
Methyl palmitate is a fatty acid methyl ester, which shows potential anti-inflammatory and antifibrotic effects by preventing bleomycin-induced lung inflammation and inhibiting the nuclear factor kappa-β pathway(NF-κB).
(R)-(+)-α-Lipoic acid, ≥98.0% (HPLC), MilliporeSigma™ Supelco™
α-Lipoic acid is an antioxidant which is generally present in plants, animals and many other microorganisms.
Granisetron Hydrochloride Pharmaceutical Secondary Standard, MilliporeSigma™ Supelco™
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
Pioglitazone hydrochloride Pharmaceutical Secondary Standard, MilliporeSigma™ Supelco™
