For professionals in the chemical industry, understanding the precise technical specifications and quality control measures of intermediates is fundamental to successful synthesis and application. 4-Fluoro-2-methoxyaniline (CAS 450-91-9) is no exception. As a critical building block, its performance in pharmaceutical, agrochemical, and dye manufacturing hinges on meeting rigorous quality benchmarks. This guide outlines the essential specifications and the importance of quality control when you buy 4-Fluoro-2-methoxyaniline.

Key Technical Specifications

When sourcing 4-Fluoro-2-methoxyaniline, several technical specifications are crucial for B2B buyers. These typically include:

  • Purity: This is arguably the most critical parameter. High-purity grades, often exceeding 98% or 99% as determined by Gas Chromatography (GC) or High-Performance Liquid Chromatography (HPLC), are standard for pharmaceutical and sensitive chemical applications. A reliable 4-Fluoro-2-methoxyaniline supplier will clearly state the purity level and the analytical method used.
  • Appearance: The product is typically described as a colorless to brown clear liquid. Any significant deviation from this description might indicate contamination or degradation.
  • Molecular Formula and Weight: C7H8FNO, with a molecular weight of approximately 141.14 g/mol. These are fundamental identifiers.
  • CAS Number: 450-91-9. This unique identifier is essential for accurate identification and regulatory compliance.
  • Physical Properties: Information such as boiling point (around 215 °C) can be important for process design.
  • Packaging: Standard packaging is often 25kg/drum, but suppliers may offer flexible options as per client requests.

The Importance of Quality Control (QC)

A robust quality control system is what differentiates a reliable 4-Fluoro-2-methoxyaniline manufacturer from others. QC processes ensure that every batch of the chemical consistently meets the defined specifications. This involves:

  • Raw Material Inspection: Verifying the quality of incoming raw materials used in the synthesis.
  • In-Process Monitoring: Conducting tests during various stages of the manufacturing process to ensure the reaction is proceeding as expected.
  • Final Product Testing: Comprehensive analysis of the finished product using validated analytical methods (GC, HPLC, NMR, etc.) to confirm purity, identity, and the absence of critical impurities.
  • Documentation: Providing Certificates of Analysis (CoA) with each batch, which details the test results against the established specifications. This document is vital for B2B clients for their own quality assurance and regulatory needs.

Partnering for Quality

When you seek to purchase 4-Fluoro-2-methoxyaniline, choosing a supplier that emphasizes transparency in its QC processes is key. A well-documented CoA is not just a formality; it is a guarantee of the product's suitability for your intended application. By understanding these technical details and prioritizing suppliers committed to rigorous quality control, businesses can ensure they obtain the high-performance intermediates necessary for successful product development and manufacturing.
