Chromatography Standards
L-Leucine, Pharmaceutical Secondary Standard, Certified Reference Material, MilliporeSigma™ Supelco™
Leucine is a non-glucogenic, essential amino acid and a structural component of proteins.
Poly(dimethylsiloxane), Average Mw 95,000 (Typical), Average Mn 50,000 (Typical), MilliporeSigma™ Supelco™
Poly(dimethylsiloxane) [PDMS] is a polymer. It is a stable silicone rubber. It has been used as ion selective membrane for ion-sensitive field-effect transistors, as spring material in accelerometers, elastomer on a tactile sensor and as flexible encapsulation material in decouple sensors.
Octocrylene 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.
Ammelide, ≥98.0% (GC), MilliporeSigma™ Supelco™
Ammelide can be synthesized via hydrolysis of 2-amino-4,6-dichloro-s-triazine in the presence of acid or base or by the reaction between urea and cyanogen iodide at 130-140 degrees.
TraceCERT™ L-Lysine monohydrochloride, MilliporeSigma™ Supelco™
L-Lysine monohydrochloride is generally used as a food and feed supplement.It can also find applications in medicine and pharmaceutical industries.L-Lysine monohydrochloride can be produced via sugar fermentation by modified microorganisms.
Sitagliptin Phosphate Pharmaceutical Secondary Standard, MilliporeSigma™ Supelco™
An anti-diabetic (antihyperglycemic) drug of the dipeptidyl peptidase-4 (DPP-4) class. Inhibition of the enzyme DPP-4 is thought to increase Glucagon-like peptide-1 (GLP-1) which inhibits glucagon release, stimulates insulin release and lowers blood glucose.
