CAS:Ethylene terephthalate (ET) is a polymer that is used in the textile industry. ET is made by the reaction of ethylene glycol with terephthalic acid, which results in the formation of linear polyesters. This process can be done as a batch or continuous process. The polymerization process starts by heating the reactants and then adding an appropriate catalyst to initiate the reaction. This step is called “extrusion” and it involves forcing the reactants through a small hole under high pressure, which creates long strings of molecules of polyester. After this, the polymer strands are heated to remove any remaining water and are stretched out into long fibers under tension. These fibers are then drawn to make them thinner and stronger before they are cut into lengths. Finally, they are wound onto spools for later use.Formula:C40H16D16O16Purity:Min. 95%Molecular weight:784.77 g/molN-Formylcytisine

CAS:Controlled ProductApplications Lablled Caffeine (C080100). Caffeine is a bitter, white crystalline xanthine alkaloid that acts as a stimulant drug and a reversible acetylcholinesterase inhibitor. Caffeine is found in varying quantities in the seeds, leaves, and fruit of some plants, where it acts as a natural pesticide that paralyzes and kills certain insects feeding on the plants. In humans, caffeine acts as a central nervous system stimulant, temporarily warding off drowsiness and restoring alertness. Caffeine is a cardiac and respiratory stimulant; diuretic. Caffeine is toxic at sufficiently high doses. Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package References Zubair, U.M., et al.: Anal.

CAS:Controlled Product6-Hydroxy melatonin is a metabolite of the hormone melatonin. It is used as a research and development impurity standard for drug product, as well as a custom synthesis. 6-Hydroxy melatonin is synthesized from the amino acid tryptophan, which is converted to serotonin in the pineal gland by the enzyme tryptophan hydroxylase. This conversion occurs through two steps: tryptophan hydroxylase converts tryptophan to 5-hydroxytryptamine (serotonin), and then 5-hydroxytryptamine to 6-hydroxytryptamine (6-OHMT). 6-OHMT can be methylated to form 6-methoxyindoleacetic acid (6-MITA) or oxidized to form melatonin.Formula:C13H12D4N2O3Purity:Min. 95%Molecular weight:252.3 g/molPyridoxine EP Impurity B HCl
