For any B2B procurement in the chemical industry, especially for critical intermediates like 2,4-Dichloro-3-fluoronitrobenzene (CAS 393-79-3), quality assurance and precise specifications are non-negotiable. Chemical manufacturers and suppliers must adhere to stringent standards to ensure that the materials they provide meet the demanding requirements of pharmaceutical, agrochemical, and fine chemical synthesis. This article outlines the key aspects of quality assurance and the typical specifications expected for this important compound.

Understanding Critical Specifications

When procuring 2,4-Dichloro-3-fluoronitrobenzene, buyers should pay close attention to several key parameters. The most fundamental is purity, with most applications requiring a minimum of 97% purity, often determined by Gas Chromatography (GC) or High-Performance Liquid Chromatography (HPLC). The presence of impurities, even in small amounts, can significantly impact downstream reactions, leading to lower yields, unwanted side products, and difficulties in purification. Therefore, suppliers must provide a detailed Certificate of Analysis (COA) with each batch, clearly stating the purity and identifying any known impurities.

Other important specifications include:

  • Chemical Identity: Confirmation of the CAS Number (393-79-3), Molecular Formula (C6H2Cl2FNO2), and Molecular Weight (209.99 g/mol) through analytical techniques.
  • Physical Appearance: Described typically as clear (liquid or solid), with specific color requirements if applicable.
  • Moisture Content: Low moisture levels are often critical, usually measured by Karl Fischer titration.
  • Storage Conditions: Manufacturers will specify optimal storage to maintain product integrity, often recommending cool, dry, and well-ventilated areas, away from incompatible materials.

Quality Control Processes by Manufacturers

Reputable manufacturers implement rigorous quality control (QC) protocols throughout the production process. This typically includes:

  • Raw Material Inspection: Ensuring the quality and purity of incoming raw materials, such as 2,6-dichlorofluorobenzene, sulfuric acid, and nitric acid, is the first step in producing a high-quality intermediate.
  • In-Process Monitoring: Regular sampling and analysis during the synthesis of 2,4-Dichloro-3-fluoronitrobenzene to monitor reaction progress and identify any deviations from standard operating procedures.
  • Final Product Testing: Comprehensive testing of the finished product to confirm it meets all specified parameters before packaging and dispatch. This includes analytical methods like GC, HPLC, NMR, and Mass Spectrometry.
  • Batch Traceability: Maintaining detailed records for each production batch, allowing for complete traceability from raw materials to the final product.
