In the dynamic field of drug discovery and development, the availability of high-quality chemical intermediates is indispensable. tert-Butyl (4-aminophenyl)carbamate (CAS 71026-66-9) stands out as a critical building block, enabling chemists to synthesize complex molecules with therapeutic potential. This article delves into the properties, applications, and sourcing considerations for this vital compound, assisting R&D scientists and formulation chemists.

Understanding the Chemical Profile

tert-Butyl (4-aminophenyl)carbamate, also known by synonyms such as 4-(tert-Butoxycarbonylamino)aniline, possesses the molecular formula C11H16N2O2 and a molecular weight of 208.26 g/mol. It is typically supplied as a beige to brownish crystalline powder with a purity of 99% or higher. This precise chemical profile is essential for its function as an intermediate in organic synthesis, particularly within the demanding environment of pharmaceutical research.

Applications in Pharmaceutical R&D

The primary utility of tert-Butyl (4-aminophenyl)carbamate lies in its role as a versatile intermediate in the synthesis of Active Pharmaceutical Ingredients (APIs). Its structure, featuring both an amine group and a protected amine group (via the tert-butoxycarbonyl, or Boc, group), allows for selective chemical modifications. This makes it ideal for:

• Building Complex Molecular Scaffolds: Researchers can strategically functionalize the amine group or deprotect the Boc-protected amine to introduce various substituents, leading to diverse molecular architectures.
• Peptidomimetic Synthesis: The carbamate linkage can be employed in the design of peptidomimetics, which are compounds that mimic the structure and function of peptides but offer improved stability and bioavailability.
• Synthesis of Heterocyclic Compounds: It serves as a precursor for various heterocyclic compounds that are common motifs in many pharmaceutical agents.

Sourcing High-Quality Intermediates

For R&D scientists, the quality of starting materials directly influences the success of their experiments. When looking to buy tert-Butyl (4-aminophenyl)carbamate, it is vital to partner with reliable manufacturers and suppliers. Key factors to consider include:

• Purity Assurance: Always seek material with a guaranteed purity of ≥99%. This ensures predictable reactivity and minimizes the risk of impurities affecting your synthesis results.
• Supplier Reputation: Identify suppliers with a strong reputation in the fine chemical and pharmaceutical intermediate markets. Manufacturers based in China are often a cost-effective choice, provided they maintain high quality standards.
• Technical Support: A good supplier will offer technical data sheets and may provide support for synthesis-related queries.
• Consistent Availability: For ongoing research projects, a consistent supply of the intermediate is crucial.

Obtaining Quotes and Samples

To procure tert-Butyl (4-aminophenyl)carbamate, initiating an inquiry with potential suppliers is the first step. Provide your specific needs, including quantity, purity, and desired packaging. Many suppliers will provide a quote that includes pricing, availability, and lead times. Requesting a sample for in-house testing before committing to a larger purchase is a prudent strategy for any R&D team.

By carefully selecting your supplier and ensuring the quality of tert-Butyl (4-aminophenyl)carbamate, you can significantly enhance the efficiency and success rate of your drug discovery efforts. This intermediate is a testament to the critical role specialized chemicals play in advancing pharmaceutical science.
