It has the molecular formula C\u2083H\u2086Br\u2082 and a molecular weight of 201.89 g\/mol. Common synonyms include trimethylene dibromide, 1,3-propylene dibromide, and \u03c9,\u03c9&#8217;-dibromopropane.<\/p>\n<h3 dir=\"auto\">Physical and Chemical Properties<\/h3>\n<ul dir=\"auto\">\n<li><strong>Appearance<\/strong>: Colorless to slightly yellow liquid with a sweet odor.<\/li>\n<li><strong>Melting Point<\/strong>: -34.4 \u00b0C.<\/li>\n<li><strong>Boiling Point<\/strong>: Approximately 165\u2013167 \u00b0C at atmospheric pressure; lower under reduced pressure (e.g., 63\u201363.5 \u00b0C at 26 mmHg, 76\u201377 \u00b0C at 40 mmHg).<\/li>\n<li><strong>Density<\/strong>: 1.977 g\/cm\u00b3 at 20 \u00b0C.<\/li>\n<li><strong>Refractive Index<\/strong>: 1.522.<\/li>\n<li><strong>Solubility<\/strong>: Soluble in organic solvents such as ether, acetone, and chloroform; insoluble in water.<\/li>\n<li><strong>Stability and Reactivity<\/strong>: Decomposes upon prolonged heating, partially converting to 1,2-dibromopropane; boiling with water produces propylene glycol. It can release toxic and corrosive fumes when decomposed.<\/li>\n<\/ul>\n<h3 dir=\"auto\">Uses<\/h3>\n<p dir=\"auto\">This compound serves primarily as an intermediate in organic synthesis. It is used to form C\u2083-bridged compounds through reactions like C-N coupling. Specific applications include:<\/p>\n<ul dir=\"auto\">\n<li>Production of dyestuffs, pharmaceuticals, and cyclopropane.<\/li>\n<li>As a herbicide in some contexts.<\/li>\n<li>In the preparation of specialized compounds, such as chiral geminal dicationic ionic liquids and 1,3-bis(1-7-chloro-4-quinolyl-4-piperazinyl)propane. It is typically intended for research and development purposes, not for medicinal, household, or other non-R&amp;D uses.<\/li>\n<\/ul>\n<h3 dir=\"auto\">Safety and Hazards<\/h3>\n<p dir=\"auto\">1,3-Dibromopropane is classified as a flammable liquid and poses health risks. Key hazards include:<\/p>\n<ul dir=\"auto\">\n<li><strong>Toxicity<\/strong>: Toxic if swallowed; harmful upon skin contact or inhalation. It can cause inflammation of the skin and may aggravate pre-existing dermatitis.<\/li>\n<li><strong>Irritation<\/strong>: Causes skin irritation, serious eye irritation, and potential respiratory irritation.<\/li>\n<li><strong>Carcinogenicity<\/strong>: Not identified as a probable, possible, or confirmed human carcinogen by IARC (at levels \u22650.1%).
