Isophthalaldehyde, identified by CAS number 626-19-7, is a crucial organic compound widely used as a versatile intermediate in chemical synthesis. Understanding its fundamental properties is key for procurement managers and R&D scientists when selecting this material for their specific applications. This article explores the essential characteristics of Isophthalaldehyde and provides guidance on how to purchase it effectively from reputable sources.

Key Physical and Chemical Properties of Isophthalaldehyde

Isophthalaldehyde typically presents as a white to slightly yellow crystalline powder, often described as needle-like. This physical form is consistent with its melting point, which is generally reported in the range of 87-88 °C (lit.). Its relatively low melting point indicates it is a solid at standard room temperatures but can be easily processed in many synthesis setups.

Chemically, Isophthalaldehyde (C8H6O2) has a molecular weight of 134.13 g/mol. While it has a slight solubility in water, it is more soluble in organic solvents such as chloroform and ethyl acetate, which is a common characteristic for aromatic aldehydes and dictates its handling and reaction media preferences.

The compound is noted as being air-sensitive to some extent, which suggests that proper storage conditions, such as keeping it in tightly sealed containers away from prolonged exposure to air, are important to maintain its quality. Stability is generally good under recommended storage temperatures (below +30°C), but it is incompatible with strong oxidizing agents, a standard precaution for most organic aldehydes.

Applications Driving Demand for Isophthalaldehyde

The demand for Isophthalaldehyde stems from its utility in various synthesis routes. It serves as a critical building block in:

  • Organic Synthesis: As a bifunctional reagent, it enables the creation of diverse organic molecules through reactions like Schiff base formation and Knoevenagel condensations.
  • Pharmaceutical Development: It acts as an intermediate in the synthesis of complex pharmaceutical compounds and APIs.
  • Material Science: Its structure can be incorporated into polymers, dyes, and other functional materials.

When seeking to buy Isophthalaldehyde, it is essential to match the purity and physical form to your specific application requirements.

Where to Purchase Isophthalaldehyde (CAS 626-19-7)

For reliable procurement, it is recommended to source Isophthalaldehyde from experienced manufacturers and suppliers who can guarantee product quality and consistent availability. When looking to purchase Isophthalaldehyde, consider suppliers who provide:

  • High Purity Grades: Ensure the product meets your purity specifications (e.g., ≥97.5% by GC).
  • Detailed Specifications: Access to melting point data, solubility information, and spectral data (NMR, IR) is crucial for verification.
  • Secure Packaging & Storage: Products should be packaged to maintain stability during transport and storage.
  • Competitive Pricing: Compare Isophthalaldehyde prices from different suppliers, balancing cost with quality assurance.

Working with a dedicated Isophthalaldehyde supplier, particularly those with manufacturing capabilities in regions like China, can offer significant advantages in terms of cost and volume. Always inquire for quotes and request samples to confirm product suitability before placing bulk orders. This due diligence ensures you receive the best value and quality for your chemical needs.
