Understanding the chemical properties and reactivity of key intermediates is fundamental for chemists involved in drug discovery and development. Ethyl 4-chloro-3-trifluoromethylphenylcarbamate (CAS 18585-06-3) is a compound of significant interest due to its versatile nature and its role as a precursor in synthesizing complex organic molecules, most notably Sorafenib. NINGBO INNO PHARMCHEM CO.,LTD. provides this essential intermediate, and understanding its chemical characteristics can greatly assist researchers in its application and procurement.

Molecular Structure and Physical Properties

Ethyl 4-chloro-3-trifluoromethylphenylcarbamate has the molecular formula C₁₀H₉ClF₃NO₂ and a molecular weight of approximately 267.63 g/mol. Its structure features a phenyl ring substituted with a chlorine atom at the 4-position and a trifluoromethyl group at the 3-position. Attached to the phenyl ring is an ethyl carbamate functional group (-NHCO₂Et). The presence of the electronegative chlorine atom and the strongly electron-withdrawing trifluoromethyl group significantly influences the electron density and reactivity of the aromatic ring and the carbamate moiety.

Key physical properties often reported include:

  • Appearance: Typically a liquid.
  • Boiling Point: Around 252.5°C at 760 mmHg.
  • Flash Point: Approximately 106.5°C.
  • Density: Around 1.402 g/cm³.

These properties are essential for handling, storage, and process design when working with the compound. As a reliable supplier, we ensure these specifications are met.

Chemical Reactivity and Transformations

The chemical reactivity of Ethyl 4-chloro-3-trifluoromethylphenylcarbamate is dictated by its functional groups:

  • Carbamate Group: The carbamate linkage (-NH-C(=O)-O-) is relatively stable but can undergo hydrolysis under strong acidic or basic conditions, yielding the parent amine and ethyl carbonate derivatives. This stability is often advantageous compared to esters.
  • Aromatic Ring: The electron-withdrawing substituents (Cl and CF₃) deactivate the phenyl ring towards electrophilic aromatic substitution. However, nucleophilic aromatic substitution at the chlorine atom might be possible under specific, harsh conditions.
  • Trifluoromethyl Group: The CF₃ group is generally inert to most common organic reactions but contributes significantly to the molecule's electronic properties and lipophilicity.

These reactivity profiles make it a valuable building block. Researchers can utilize it in coupling reactions, functional group transformations, or as a scaffold for further molecular elaboration. For those looking to buy this intermediate, understanding its potential reactions aids in planning synthetic routes.
