CAS 10035-10-6: Bromure d'hydrogène
Description :
Bromure d'hydrogène (HBr) est un gaz incolore à température ambiante, caractérisé par son odeur âcre et sa nature corrosive. C'est une molécule diatomique composée d'hydrogène et de brome, et elle se dissout facilement dans l'eau pour former de l'acide bromhydrique, un acide fort qui se dissocie complètement en solution aqueuse. HBr est hautement soluble dans les solvants polaires et peut réagir vigoureusement avec des bases et des agents oxydants. Ses propriétés physiques incluent un point d'ébullition qui lui permet d'exister sous forme de gaz dans des conditions standard, tandis que son poids moléculaire contribue à sa densité supérieure à celle de l'air. En termes de sécurité, Bromure d'hydrogène est classé comme une substance dangereuse ; il peut provoquer une irritation respiratoire sévère et des dommages aux muqueuses en cas d'exposition. De plus, il est utilisé dans diverses applications industrielles, y compris la synthèse de composés de brome, de produits pharmaceutiques et comme catalyseur dans des réactions organiques. Une manipulation et un stockage appropriés sont essentiels en raison de sa nature corrosive et toxique.

CAS :Hydrobromic acid is a strong acid that is a potent inhibitor of acetylcholinesterase, which is an enzyme required for the breakdown of acetylcholine. It also has been shown to inhibit the activity of dipeptidyl-peptidase IV (DPP-IV). Hydrobromic acid can be used in analytical methods as it can be detected by electrochemical impedance spectroscopy. This compound has been shown to have a cholinergic effect and to act as a methyltransferase inhibitor. It also has been shown to be effective in pharmacological treatment of congestive heart failure and may act through the epidermal growth factor receptor or cell factor.Formule :HBrDegré de pureté :Min. 95%Masse moléculaire :80.91 g/molHydrobromic Acid, ca 48 wt. % Solution in Water (Tech.)

CAS :Hydrobromic acid is a highly corrosive, toxic and irritating liquid. It reacts with water (H2O) to form hydrobromic acid and hydrogen fluoride gas. Hydrobromic acid is a weak acid that can be used as an oxidizing agent in organic syntheses. The reaction solution formed when hydrobromic acid is added to water has been shown to have cell factor activity in vitro. In vivo human studies have determined that this reaction solution has a phase transition temperature of about -6°C. The anhydrous sodium salt of hydrobromic acid can also be prepared by reacting hydrogen bromide with anhydrous sodium hydroxide at 100°C in the presence of sulfur dioxide gas.Formule :HBrDegré de pureté :(Titration) Min. 48%Couleur et forme :Clear LiquidMasse moléculaire :80.91 g/molHydrobromic Acid, 31-34% in Glacial Acetic Acid
