For procurement managers and R&D scientists in the chemical and pharmaceutical industries, a thorough understanding of a compound's properties and specifications is fundamental to successful acquisition and application. 1-Bromo-5-Fluoropentane (CAS 407-97-6) is a key intermediate, and knowing its detailed characteristics ensures optimal utilization in synthesis and research.

Chemical Identity and Structure

1-Bromo-5-Fluoropentane, also known by synonyms such as 5-Fluoropentyl bromide, is a halogenated alkane with the molecular formula C5H10BrF. Its CAS Registry Number is 407-97-6. The molecule features a five-carbon chain with a bromine atom at one end and a fluorine atom at the other, making it a bifunctional building block. This structure allows for selective reactivity at either the bromine or fluorine site, or through reactions involving both.

Key Physical and Chemical Properties

Reputable manufacturers typically provide the following specifications for 1-Bromo-5-Fluoropentane:

  • Appearance: Colorless to yellowish liquid. This visual characteristic is a primary indicator of purity.
  • Assay (Purity): Generally specified as ≥99% or ≥99.5% minimum. High purity is critical for pharmaceutical applications to avoid unwanted side reactions or impurities in the final product.
  • Molecular Weight: Approximately 169.04 g/mol.
  • Boiling Point: Around 162°C at standard atmospheric pressure. This property is important for distillation and purification processes.
  • Density: Typically around 1.303 to 1.360 g/cm³ at 25°C. Density information is useful for volumetric calculations and material handling.
  • Refractive Index: Often cited in the range of 1.424 to 1.440. This is another parameter used for identification and quality control.
  • Flash Point: Approximately 50.1°C, indicating it is a combustible liquid and requires appropriate safety measures.
  • Moisture Content: Usually specified as ≤0.3%, as excessive moisture can interfere with certain reactions, particularly those involving organometallic reagents.

Applications Driving Specification Requirements
