Ammonium formate


Product Name: Ammonium Formate
CAS: 540-69-2
Molecular Formula: CH5NO2
Formula Weight: 63.06
Description:
Ammonium formate, NH 4 HCO 2, is the ammonium salt of formic acid. It is colorless, crystalline solid hygroscopic.
Pure ammonium formate decomposes into formamide and water when heated, which is its main use in industry. Formic acid can also be obtained by reaction of ammonium formate with a dilute acid, and also because the formic acid formate of formic acid is prepared, it can serve as a formic form of formic acid storage.
Ammonium formate can also be used in the reduction of carbon (Pd / C) of the functional groups used in werden.Moniumformiat can be used for the reductive amination of aldehydes and ketones (Leuckart reaction). It can be used as a buffer in high performance liquid chromatography (HPLC) and is suitable for use with liquid chromatography / mass spectroscopy (LC / MS).

Salbutamol price


Product Name: salbutamol
CAS: 18559-94-9
Molecular formula: C13H21NO3
Formula Weight: 239.31
Description:
Salbutamol (DCI) or salbutamol (USAN) is a short-acting β2-adrenergic receptor agonist, which is used for the relief of bronchospasm under conditions such as asthma and chronic obstructive pulmonary disease.
Salbutamol sulphate is usually administered by inhalation for direct effect on the smooth shell of the bronchi. This is usually a metered dose inhaler (MDI), nebulizers or other proprietary dispensing devices achieved (eg B. Rotahaler or AUTOHALER). These delivery forms the maximum effect of salbutamol within five to twenty minutes dosing can take place, if some relief is seen immediately. Salbutamol may also be administered orally as an inhalant or intravenous.

Vasopressin for sale


Product Name: vasopressin
CAS RN 50-57-7
Molecular Formula: C46H65N13O12S2
Weight of formula: 1056.22
Description:
Arginine vasopressin (AVP), also known as vasopressin or antidiuretic hormone vasopressin (ADH), is a hormone in most mammals, including humans, found. Vasopressin is a peptide hormone that controls the reabsorption of molecules in the kidneys of the kidneys, affecting the permeability of the tissue. It also increases peripheral vascular resistance, which in turn increases arterial blood pressure. It plays a key role in the homeostasis and regulation of water, glucose, and salts in the blood. It comes from a Preprohormonvorläufer which is synthesized in the hypothalamus and stored in vesicles in the posterior pituitary gland. The major part is stored in the posterior pituitary gland to be released into the bloodstream; However, some AVPs are released directly into the brain.
