This article aims to shed light on its properties, applications, and most importantly, guide procurement specialists and chemists in identifying and engaging with dependable suppliers and manufacturers.

Understanding 1-Bromo-4-Chlorobutane: Properties and Uses

1-Bromo-4-chlorobutane is an organic compound classified as a dihalogenated alkane. Its molecular formula is C4H8BrCl, and it is characterized by a four-carbon chain with a bromine atom attached to one terminal carbon and a chlorine atom attached to the other. This unique bifunctional structure imparts specific reactivity, making it a valuable building block in organic synthesis.

Key properties include:

  • Appearance: Typically a colorless to pale yellow liquid.
  • Purity: Commonly available with an assay of 99% or higher, crucial for precise synthesis.
  • Reactivity: The bromine atom is generally more reactive than the chlorine atom in nucleophilic substitution reactions, allowing for selective chemical transformations.

Its primary applications lie in:

  • Pharmaceutical Intermediates: It serves as a critical precursor in the synthesis of many active pharmaceutical ingredients (APIs), contributing to the construction of complex drug molecules.
  • Fragrance and Flavor Industry: Used in the creation of specific aroma chemicals and flavor compounds.
  • Fine Chemical Synthesis: A versatile reagent for developing specialty chemicals and materials requiring specific alkyl chain modifications.

Navigating the Supplier Landscape for 1-Bromo-4-Chlorobutane

For businesses looking to buy 1-Bromo-4-chlorobutane, particularly from international markets like China, selecting the right supplier is paramount. Key considerations when evaluating potential suppliers and manufacturers include:

  • Quality Assurance: Ensure the supplier provides a Certificate of Analysis (COA) for each batch, detailing product purity and specifications. Reputable manufacturers will have robust quality control systems in place.
  • Production Capacity and Stability: A supplier with a significant production capacity (e.g., 200 tons/month) and a history of reliable delivery indicates they can meet ongoing demands.
  • Experience and Reputation: Look for suppliers with extensive export experience and positive feedback from other buyers. This often signifies a well-established and trustworthy operation.
  • Pricing and Minimum Order Quantity (MOQ): Obtain quotes from multiple suppliers and compare them, considering that bulk purchases often come with better pricing. Understand the MOQ to ensure it aligns with your needs.
  • Customer Service: Responsive communication and willingness to provide samples or address inquiries are indicators of good supplier partnership.

When you need to source CAS 6940-78-9, it is advisable to engage directly with manufacturers.
