For R&D scientists and chemists working on novel material synthesis or complex organic molecules, a thorough understanding of a chemical intermediate's properties is fundamental. 1-Bromo-3,7-dimethyloctane (CAS 3383-83-3) is one such compound that offers specific chemical characteristics beneficial for various research applications. This article details its key properties and discusses how they influence its use in synthesis, emphasizing the importance of sourcing from reliable manufacturers.

Key Chemical Properties of 1-Bromo-3,7-dimethyloctane

Understanding the physical and chemical traits of 1-Bromo-3,7-dimethyloctane is crucial for effective utilization in R&D:

  • Molecular Structure: With the formula C10H21Br and a molecular weight of 221.18 g/mol, it features a branched eight-carbon chain with a bromine atom at the terminal position. This structure dictates its reactivity and physical behavior.
  • Physical State: Typically, it is supplied as a liquid. Sources indicate it is a clear to light yellow liquid, with a density of approximately 1.066 g/mL at 20°C. This liquid form facilitates easy handling and measurement in laboratory settings.
  • Boiling Point: The boiling point is often reported around 135-140 °C at 10 mmHg. This relatively high boiling point under vacuum suggests good thermal stability for many reaction conditions, though it’s always advisable to consult specific supplier data.
  • Reactivity: As a primary alkyl bromide, 1-Bromo-3,7-dimethyloctane is susceptible to nucleophilic substitution (SN2 reactions) and can also undergo elimination reactions under certain conditions. Its reactivity makes it a valuable starting material for introducing the 3,7-dimethyloctyl group into various molecular frameworks.
  • Solubility: Like many organic halides with significant hydrocarbon character, it is expected to be soluble in common organic solvents but poorly soluble in water.

Ensuring Quality When Purchasing

Researchers looking to buy 1-Bromo-3,7-dimethyloctane must prioritize purity and reliable specifications. Working with experienced manufacturers, especially those in China, allows for access to high-quality products with detailed documentation. When you inquire about purchasing, always ask for the Certificate of Analysis (COA) to verify purity (typically 97% minimum) and other critical parameters. This diligence ensures that the chemical intermediate meets the stringent requirements of R&D projects, contributing to accurate and reproducible scientific outcomes.
