Description

Product Overview

1-Bromobutane (also known as n-Butyl Bromide or Butyl Bromide) CAS No.: 109-65-9 , with the chemical formula C₄H₉Br and a molecular weight of 137.02 g/mol. It is a colorless to light yellow liquid with a characteristic or pleasant odor. This compound belongs to the class of alkyl halides and is primarily used in organic synthesis and as a solvent, though it is flammable and subject to safety regulations due to its irritant and environmental properties.

Properties

1-Bromobutane exhibits the following key physical and chemical properties:

  • Physical State: Liquid (at room temperature).
  • Appearance: Clear colorless to light yellow liquid.
  • Odor: Characteristic or pleasant odor.
  • Melting Point: -112 °C.
  • Boiling Point: 101-102 °C.
  • Density: 1.27 g/mL (at 25 °C).
  • Solubility: Slightly soluble in water (0.6 g/L); miscible with organic solvents like ethanol, ether, and chloroform.
  • Stability: Stable under normal conditions; flammable with a flash point of 10-23 °C; incompatible with strong oxidants and strong bases.
  • Toxicity: Moderately toxic; LD50 oral in rat: 2761 mg/kg; causes irritation to skin, eyes, and respiratory tract; may cause respiratory irritation, headache, nausea; toxic to aquatic life with long-lasting effects.

Applications

The primary applications of 1-bromobutane include:

  • Organic Synthesis Intermediate: Used as an alkylating agent in the production of pharmaceuticals (e.g., procaine and tetracaine), agrochemicals, and other organic compounds; precursor for Grignard reagents and organometallics like n-butyllithium.
  • Solvent: Employed for cleaning, degreasing, and extraction in industrial and laboratory processes.
  • Other: Acts as a derivatization reagent for functional groups (e.g., amino acids to improve hydrophobicity); used as an internal standard in analytical techniques like gas chromatography for quantifying compounds in samples such as human urine.

Classification

The following table outlines the classification of 1-bromobutane based on chemical properties, uses, and regulations:

Classification Type Specific Category Description
Chemical Class Alkyl Halide (Bromoalkane) A primary brominated alkane, reactive in nucleophilic substitution reactions (e.g., SN2).
Usage Class Organic Synthesis Reagent/Solvent Primarily an intermediate for chemical synthesis and cleaning/degreasing applications.
Hazard Class Flammable Liquid (UN 1126); Irritant Flammable (flash point 10-23 °C); irritating to skin, eyes, and respiratory system (GHS: H225, H315, H319, H335, H411); toxic to aquatic life; packing group II.
Regulatory Class Controlled Chemical (REACH, TSCA) Registered under EU REACH (EC 203-691-9) and US TSCA; subject to environmental release controls and hazardous substance regulations (WGK 2 in Germany).
