For professionals in the chemical and pharmaceutical industries, the precise specifications and purity of raw materials directly impact the success of synthesis and product quality. This article focuses on 2,3-Dimethylbromobenzene (CAS 576-23-8), examining its essential properties and the importance of high purity for its applications.

Key Identifiers and Properties of 2,3-Dimethylbromobenzene

2,3-Dimethylbromobenzene, also known as 3-Bromo-o-xylene, is a haloaromatic compound with the CAS number 576-23-8. Its molecular formula is C8H9Br, and it has a molecular weight of 185.06 g/mol. Typically, it is supplied as a clear, colorless to pale yellow liquid.

Critical properties that buyers should verify from their supplier include:

  • Purity: This is arguably the most crucial specification. For pharmaceutical and fine chemical synthesis, a purity of 98% or higher, often determined by Gas Chromatography (GC), is standard. Higher purities minimize side reactions and improve yields.
  • Appearance: A clear, colorless to pale yellow liquid indicates proper handling and minimal degradation. Significant coloration or turbidity might suggest impurities or degradation.
  • Boiling Point: Approximately 214°C at atmospheric pressure. This is important for distillation and reaction temperature control.
  • Density: Around 1.365 g/mL at 25°C. This metric is useful for volume-to-mass calculations and process design.
  • Flash Point: Typically around 80°C (closed cup) or 177°F. This is a key safety parameter for storage and handling.

Why High Purity Matters

The utility of 2,3-Dimethylbromobenzene as an intermediate relies heavily on its purity:

  • Pharmaceutical Synthesis: In the development of Active Pharmaceutical Ingredients (APIs), even minor impurities can affect the safety and efficacy of the final drug. High-purity intermediates ensure that only the desired molecular transformations occur. Companies seeking to buy pharmaceutical-grade intermediates must prioritize purity.
  • Agrochemical Formulations: Similarly, in agrochemicals, impurities can lead to reduced product performance, phytotoxicity, or environmental concerns.
  • Organic Synthesis: For researchers and chemists, using pure starting materials leads to cleaner reactions, higher yields, and more reliable experimental results. This efficiency translates to cost savings and faster research cycles.

Procuring High-Quality 2,3-Dimethylbromobenzene

When searching for a manufacturer of 2,3-Dimethylbromobenzene (CAS 576-23-8), always request a detailed Certificate of Analysis (CoA) that confirms the purity and other key specifications. Reputable suppliers, such as NINGBO INNO PHARMCHEM CO.,LTD. from China, are transparent about their product quality and provide the necessary documentation. Understanding these specifications is not just about quality control; it’s about ensuring the safety, efficiency, and success of your chemical processes.

By prioritizing suppliers who offer verifiable high-purity 2,3-Dimethylbromobenzene and detailed technical specifications, you can confidently advance your synthesis projects and product development.
