For procurement managers and product formulators in the chemical industry, understanding the precise specifications of raw materials is not just a matter of quality control; it's fundamental to product performance and regulatory compliance. 2-Isopropoxyphenol (CAS 4812-20-8) is a key intermediate, particularly in the agrochemical sector for the synthesis of insecticides like Propoxur. This guide aims to provide a clear overview of its critical specifications, helping buyers make informed decisions when they need to purchase this vital compound.

Key Chemical and Physical Properties: What Buyers Need to Know

When evaluating a supplier for 2-Isopropoxyphenol, several key parameters are consistently reported across reputable manufacturers. These include:

  • Appearance: Typically described as a colorless to yellow transparent liquid at room temperature. Variations in color might indicate purity levels or slight degradation, so consistency is important.
  • Purity (Assay): The minimum acceptable purity for industrial applications, especially in pesticide synthesis, is generally 98.0%. Some suppliers may offer 97% or higher grades. Always verify the assay method (e.g., GC, HPLC) mentioned by the manufacturer.
  • Moisture Content: Often specified as ≤1.0%. High moisture content can interfere with subsequent chemical reactions, particularly those involving moisture-sensitive reagents.
  • Molecular Formula: C9H12O2. This confirms the chemical identity.
  • Molecular Weight: Approximately 152.19 g/mol. This is crucial for stoichiometric calculations in formulations and synthesis.
  • CAS Number: 4812-20-8. This unique identifier is essential for accurate product identification and regulatory tracking.
  • Boiling Point: Reported around 100-102°C at 11 mmHg or 219.7°C at 760 mmHg. This property is relevant for distillation and purification processes.
  • Flash Point: Typically around 87°C. This is a critical safety parameter for handling, storage, and transportation.
  • Density: Approximately 1.03 g/mL at 25°C. Useful for volume-to-mass conversions and process design.
  • Refractive Index: Usually around 1.515. This physical property can be used as an additional quality control check.

Ensuring Quality and Reliability When You Buy 2-Isopropoxyphenol

Procuring 2-Isopropoxyphenol requires a strategic approach. Buyers should always request a detailed Certificate of Analysis (CoA) with each batch. This document should confirm that the product meets the agreed-upon specifications. When seeking a supplier, especially from regions like China where significant manufacturing capacity exists, it's advisable to look for manufacturers with established quality management systems, such as ISO certifications. Inquiry for price and availability should also include specific requirements regarding packaging (e.g., 200 kg/drum) and any custom packaging needs.

The consistent quality of 2-Isopropoxyphenol directly impacts the yield and purity of downstream products like Propoxur. Therefore, choosing a reliable manufacturer and supplier is not just about cost but also about ensuring the integrity of your own production processes. By understanding these specifications, procurement professionals can confidently source 2-Isopropoxyphenol, secure competitive pricing, and build robust supply partnerships.
