It is a colorless to pale yellow or dark brown hygroscopic liquid with a sweet, burning taste and relatively stable chemical properties, though it is toxic. This compound belongs to the class of halo alcohols and is primarily used in organic synthesis and industrial processes.<\/p>\n<h3 dir=\"auto\">Properties<\/h3>\n<p dir=\"auto\">2-Bromoethanol exhibits the following key physical and chemical properties:<\/p>\n<ul dir=\"auto\">\n<li><strong>Physical State<\/strong>: Liquid (at room temperature).<\/li>\n<li><strong>Appearance<\/strong>: Colorless to pale yellow or dark brown liquid.<\/li>\n<li><strong>Odor\/Taste<\/strong>: Mild odor; sweet, burning taste.<\/li>\n<li><strong>Melting Point<\/strong>: Not widely reported (typically low, around -50 \u00b0C based on similar compounds).<\/li>\n<li><strong>Boiling Point<\/strong>: Approximately 150 \u00b0C (decomposes partially).<\/li>\n<li><strong>Density<\/strong>: 1.59\u20131.60 g\/mL (at 20 \u00b0C).<\/li>\n<li><strong>Solubility<\/strong>: Miscible with water (forms an azeotrope); soluble in organic solvents like ethanol and ether.<\/li>\n<li><strong>Stability<\/strong>: Relatively stable but hygroscopic; incompatible with strong oxidants, acids, and bases; may decompose upon heating.<\/li>\n<li><strong>Toxicity<\/strong>: Toxic by ingestion, inhalation, and skin absorption; causes irritation to skin, eyes, and respiratory tract; classified as a hazardous substance (UN 1566, corrosive and toxic).<\/li>\n<\/ul>\n<h3 dir=\"auto\">Applications<\/h3>\n<p dir=\"auto\">The primary applications of 2-bromoethanol include:<\/p>\n<ul dir=\"auto\">\n<li><strong>Organic Synthesis Intermediate<\/strong>: Used as a building block for synthesizing pharmaceuticals, such as 2-piperidin-1-yl-ethanol via reaction with piperidine; also in selective reduction of nitroarenes using catalyst systems like PcFe(II)\/NaBH\u2084.<\/li>\n<li><strong>Solvent<\/strong>: Acts as a solvent and raw material in various organic reactions and chemical experiments.<\/li>\n<li><strong>Industrial Processes<\/strong>: Employed in the production of surfactants, pharmaceuticals, and other fine chemicals; historically involved in ethylene oxide reactions with hydrobromic acid, leading to potential exposure risks in manufacturing.<\/li>\n<li><strong>Other<\/strong>: Used in laboratory settings for bromoalkylation reactions and as a reagent in polymer chemistry.<\/li>\n<\/ul>\n<h3 dir=\"auto\">\u0410\u043d\u0433\u0438\u043b\u0430\u043b<\/h3>\n<p dir=\"auto\">The following table outlines the classification of 2-bromoethanol based on chemical properties, uses, and regulations:<\/p>\n<div dir=\"auto\">\n<div>\n<div><\/div>\n<\/div>\n<table dir=\"auto\" data-wide=\"false\">\n<thead>\n<tr>\n<th data-col-size=\"sm\">Classification Type<\/th>\n<th data-col-size=\"lg\">Specific Category<\/th>\n<th data-col-size=\"xl\">Description<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td data-col-size=\"sm\"><strong>Chemical Class<\/strong><\/td>\n<td data-col-size=\"lg\">Halo Alcohol (Bromohydrin)<\/td>\n<td data-col-size=\"xl\">A \u03b2-bromo alcohol derivative of ethylene glycol, reactive in nucleophilic substitutions and prone to forming epoxides.<\/td>\n<\/tr>\n<tr>\n<td data-col-size=\"sm\"><strong>Usage Class<\/strong><\/td>\n<td data-col-size=\"lg\">Organic Synthesis Reagent\/Solvent<\/td>\n<td data-col-size=\"xl\">Primarily an intermediate for pharmaceutical and fine chemical production;
