CAS:Rabeprazole is a proton pump inhibitor that is used to treat acid-related disorders such as gastroesophageal reflux disease and peptic ulcers. Rabeprazole inhibits the production of gastric acid by blocking the hydrogen/potassium ATPase that is found in the parietal cells of the stomach. The main mechanism of action for rabeprazole is competitive inhibition of the proton pump, which leads to decreased gastric acid secretion. Rabeprazole can be administered orally or intravenously, with a half-life of about 2 hours. It has been shown to have an effect on human liver cytochrome P450s, but does not affect the activity of recombinant cytochrome P450 3A4 (CYP3A4). In clinical studies, rabeprazole was shown to have no adverse effects on CYP3A4 activity and may even increase it slightly.Formula:C18H21N3O2SPurity:Min. 95%Color and Shape:White PowderMolecular weight:343.44 g/molDesmopressin EP Impurity F Trifluoroacetate

CAS:Tetrahydro-α-(1-naphthalenylmethyl)-2-furanpropanoic acid is a reagent that is used in analytical procedures for the determination of phosphate and potassium. Tetrahydro-α-(1-naphthalenylmethyl)-2-furanpropanoic acid can be used to determine the concentrations of phosphate and potassium in human plasma, serum, or other biological fluids. It reacts with phosphates to form an insoluble salt which can be detected by fluorimetry. Tetrahydro-α-(1-naphthalenylmethyl)-2-furanpropanoic acid can also be used as an analytical standard in high performance liquid chromatography (HPLC) to measure the concentration of phosphate.Formula:C18H20O3Purity:Min. 95%Molecular weight:284.3 g/molBalsalazide 3-isomer
CAS:Balsalazide 3-isomer (BZ3) is a diacid that is used as an anti-hypertensive drug. BZ3 has been shown to be a prodrug of balsalazide, which is converted in vivo to the active form by hydrolysis of the ester linkage. The prodrug approach was designed to provide an orally available agent for use in patients with colitis and ulcerative colitis. The synthetic process begins with the reaction of salicylic acid and bisoprolol to form the ester product, which then undergoes a second reaction with acetyl chloride to form the acyl chloride intermediate. This intermediate reacts with balsalazide and yields BZ3 when heated to high temperatures. BZ3 contains no impurities because it is synthesized from pure starting materials, whereas commercially available balsalazide may contain impurities such as salicylic acid or colitis.Formula:C17H15N3O6Purity:Min. 95%Molecular weight:357.32 g/mol
