For professionals in the chemical and pharmaceutical industries, a thorough understanding of key compounds is vital for successful operations. 2,2-Dichloro-1,1,1-trifluoroethane (CAS 306-83-2), often referred to as HCFC-123, is one such compound that demands attention due to its diverse applications and specific handling requirements. This article provides an in-depth look at its properties, core uses, and offers practical advice for procurement managers on how to effectively buy this chemical from Chinese manufacturers.

Key Properties of 2,2-Dichloro-1,1,1-trifluoroethane

HCFC-123 is characterized by its distinct physical and chemical properties. Sourced from leading suppliers, it is typically a clear, colorless liquid or gas with a slight ethereal odor. Its molecular formula is C2HCl2F3, with a molar mass of approximately 152.93 g/mol. Key physical parameters include:

  • Melting Point: -107 °C
  • Boiling Point: 27.6 °C
  • Density: 1.47 g/cm³ (liquid state)
  • Purity: Commonly available at 98% or higher, crucial for specific applications.

It is generally stable under normal temperatures and pressures, but its handling requires adherence to safety protocols due to its classification as a regulated substance and potential health impacts upon overexposure.

Primary Industrial Applications

The utility of 2,2-Dichloro,1,1,1-trifluoroethane spans several critical sectors:

  • Refrigeration: It serves as an interim replacement for CFCs in low-pressure refrigeration and HVAC systems, particularly in large centrifugal chillers. Its energy efficiency in these applications is a significant advantage.
  • Foam Blowing Agent: Used in the production of polyurethane foams, contributing to insulation properties in construction and appliances.
  • Cleaning Agent: Its solvent properties make it effective for industrial cleaning and degreasing applications.
  • Pharmaceutical Intermediate: A vital building block in the synthesis of various pharmaceutical compounds, requiring high purity and consistent quality from the manufacturer.

Given its role as an HCFC, understanding its current regulatory status and production phase-out schedules is important for long-term planning.

Strategies for Sourcing and Procurement

For procurement managers aiming to buy 2,2-Dichloro,1,1,1-trifluoroethane, focusing on Chinese manufacturers offers a competitive edge. Here are some key strategies:

  • Direct Manufacturer Engagement: Bypassing intermediaries ensures better prices and direct communication about product specifications and quality control.
  • Request for Quotation (RFQ): Submit detailed RFQs to multiple reputable Chinese chemical companies to compare pricing and terms effectively.
  • Verify Certifications and Documentation: Ensure the supplier provides Certificates of Analysis (COA), Safety Data Sheets (SDS), and any necessary compliance documentation.
  • Assess Supply Chain Robustness: Confirm the manufacturer's capacity and logistical capabilities to ensure a reliable supply chain, especially for bulk orders.

By adopting a strategic approach to sourcing, procurement professionals can secure a consistent and cost-effective supply of 2,2-Dichloro,1,1,1-trifluoroethane, supporting their production needs in refrigeration, pharmaceuticals, and beyond.
