Dichlorotrifluoroacetophenone

Updated: 2026-07-16

Overview

Dichlorotrifluoroacetophenone is a halogenated aromatic ketone primarily used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Its molecular structure, featuring chlorine and fluorine substituents, enhances its reactivity, making it valuable in complex organic reactions. The compound is typically supplied as a white to pale yellow crystalline powder, soluble in common organic solvents but not in water. Industries favor this chemical for its ability to introduce trifluoromethyl and dichloroacetyl groups into target molecules, a step critical in developing active ingredients for drugs and pesticides. Its synthesis involves multi-step halogenation and acylation processes, requiring controlled conditions to ensure yield and purity.

Physical and Chemical Properties

The compound exhibits a melting point range of 80–85°C, indicating moderate thermal stability. Its solubility profile favors organic solvents like ethanol, methanol, and acetone, while it remains insoluble in water due to its hydrophobic aromatic backbone. The presence of electronegative halogens (chlorine and fluorine) contributes to its polar character and reactivity in nucleophilic substitution reactions. Key chemical properties include its susceptibility to hydrolysis under acidic or alkaline conditions, necessitating dry storage. The trifluoromethyl group enhances lipophilicity, a trait exploited in drug design to improve membrane permeability. Analytical techniques like HPLC and GC-MS are commonly used to assess purity, which typically exceeds 95% for commercial grades.

Main Applications

Dichlorotrifluoroacetophenone serves as a versatile building block in pharmaceutical synthesis, particularly for antidepressants, antivirals, and anti-inflammatory agents. Its trifluoromethyl group is a pharmacophore in many FDA-approved drugs, enhancing metabolic stability and bioavailability. In agrochemicals, it is used to produce herbicides and fungicides with improved efficacy and environmental profiles. The compound also finds niche applications in material science, where it acts as a precursor for specialty polymers and coatings. Its halogenated structure imparts flame-retardant properties to these materials. Research institutions utilize it to develop novel fluorinated compounds, leveraging its predictable reactivity in cross-coupling and condensation reactions.

Safety and Storage

As a reactive halogenated compound, Dichlorotrifluoroacetophenone requires careful handling. PPE such as nitrile gloves, goggles, and lab coats are mandatory to prevent skin and eye contact. Inhalation risks are mitigated by using fume hoods or respirators in poorly ventilated areas. Spills should be contained with inert absorbents and disposed of as hazardous waste. Storage recommendations include airtight containers under inert gas (e.g., nitrogen) to prevent moisture absorption and degradation. Compatibility with common storage materials like glass and HDPE ensures long-term stability. Safety Data Sheets (SDS) must be reviewed for first-aid measures and fire-fighting protocols, as the compound may release toxic fumes when heated.

B2B Procurement Guide

B2B buyers should prioritize suppliers with ISO 9001 certification and documented batch-to-batch consistency. Request Certificates of Analysis (CoA) specifying purity, residual solvents, and heavy metal content. Custom synthesis options are available for large-scale orders, with lead times varying from 4–8 weeks depending on complexity. Pricing is influenced by order volume (typically sold in 25 kg drums) and purity requirements (technical grade vs. analytical grade). Logistics considerations include temperature-controlled shipping for international orders to prevent melting or degradation. Establish long-term contracts to secure supply chain stability, especially given the compound's niche market status.
