In the chemical and pharmaceutical industries, precise specifications are the bedrock of reliable synthesis and product development. For intermediates like 2,4-Diaminofluorobenzene (CAS 6264-67-1), adherence to strict quality parameters is not just a matter of preference but a necessity. This guide outlines the essential quality specifications that procurement professionals and researchers should consider when purchasing this vital compound, emphasizing the importance of sourcing from trusted manufacturers.

The Foundation: CAS Number and Chemical Identity

The first and most fundamental specification is the CAS Registry Number. For 2,4-Diaminofluorobenzene, this is 6264-67-1. This unique identifier ensures that you are acquiring the correct chemical substance, distinguishing it from isomers or related compounds. Coupled with its correct chemical name (e.g., 2,4-Diaminofluorobenzene, 4-fluoro-1,3-benzenediamine) and molecular formula (C6H7FN2), it establishes the identity of the product.

Purity: The Paramount Specification

Purity is arguably the most critical aspect of quality for any chemical intermediate. For 2,4-Diaminofluorobenzene, common purity levels offered by reputable suppliers range from 97% to 99%.

  • Minimum Purity: Always look for a minimum purity of 97%. For more sensitive applications or when aiming for higher yields and cleaner reaction profiles, 98% or 99% purity might be preferred.
  • Impurity Profile: Beyond the overall purity percentage, understanding the impurity profile is crucial. A Certificate of Analysis (CoA) should detail specific impurities and their maximum allowable limits. Common impurities might include unreacted starting materials, isomers, or degradation products.
  • Analytical Methods: Reputable manufacturers will specify the analytical methods used to determine purity, such as Gas Chromatography (GC) or High-Performance Liquid Chromatography (HPLC).

Ensuring high purity directly impacts downstream reactions, preventing unexpected side products and ensuring the efficacy and safety of the final product, especially in pharmaceutical applications.

Physical Characteristics: Appearance and Form

The physical characteristics of 2,4-Diaminofluorobenzene also provide clues about its quality and suitability for handling:

  • Appearance: The standard appearance for high-quality 2,4-Diaminofluorobenzene is a White Powder. Any significant deviation in color, such as brown or yellowing, could indicate degradation or contamination.
  • Form: As a powder, it is generally easy to handle, weigh, and dissolve. The consistency of the powder (e.g., fine vs. coarse) can sometimes be important for dissolution rates in specific solvents.

Key Physical Properties for Handling and Processing

Other important specifications that aid in safe handling and process design include:

  • Melting Point: Typically 34-37 °C. A sharp melting point within this range is indicative of high purity.
  • Boiling Point: Around 152-153 °C. This is relevant for processes involving distillation or high-temperature reactions.
  • Flash Point: Generally reported as >100 °C, indicating moderate flammability risk under normal conditions.
