For product formulation chemists, selecting the right chemical intermediates is key to developing effective and stable end products, particularly in the pharmaceutical sector. tert-Butyl (4-aminophenyl)carbamate (CAS 71026-66-9) offers unique properties that make it a valuable component in advanced formulations. This article explores its utility from a formulator's viewpoint and provides guidance on sourcing this critical material.

Understanding tert-Butyl (4-aminophenyl)carbamate for Formulation

tert-Butyl (4-aminophenyl)carbamate is a fine chemical with the formula C11H16N2O2, commonly presented as a beige to brownish crystalline powder with high purity (≥99%). Its structure incorporates a Boc-protected amine, a common protecting group in organic chemistry that can be selectively removed. This feature is particularly advantageous for formulators who need to control reaction pathways during synthesis or for incorporating specific functional groups into a larger molecule designed for a particular application.

Formulation Advantages and Applications

The utility of tert-Butyl (4-aminophenyl)carbamate extends across various formulation strategies:

• Controlled Release Systems: The Boc group can be cleaved under specific conditions, allowing for the controlled release of the amine functionality. This is valuable in designing drug delivery systems where the active agent needs to be released at a precise time or location.
• Prodrug Design: The compound can serve as a starting point for creating prodrugs. By masking or modifying the amine group, the parent compound's solubility, stability, or targeting can be improved, leading to better pharmacokinetic profiles.
• Synthesis of Functionalized Polymers: The presence of reactive sites allows for its incorporation into polymer backbones or as side chains, enabling the creation of functionalized polymers for specialized applications, including drug encapsulation or targeted delivery vehicles.
• Intermediate for Complex Formulations: Its role as a versatile intermediate means it can be used in the multi-step synthesis of complex APIs that will eventually be formulated into final dosage forms.

Sourcing Strategies for Formulators

When sourcing tert-Butyl (4-aminophenyl)carbamate for formulation development, formulators should prioritize:

• Purity and Consistency: Ensuring a consistent purity of ≥99% is vital for reproducible formulation outcomes. Variations in purity can lead to unpredictable reactions or affect the final product's stability and efficacy.
• Reliable Supply: Partnering with a trusted manufacturer or supplier in regions like China ensures a stable supply chain, critical for ongoing formulation projects and potential scale-up.
• Technical Documentation: Access to detailed technical data sheets, safety data sheets (SDS), and certificates of analysis (CoA) is essential for regulatory compliance and effective use in formulation.
• Cost-Effectiveness: Obtaining competitive pricing without compromising on quality is a key objective for formulators aiming to manage development budgets effectively.

How to Buy and Request Quotes

To procure tert-Butyl (4-aminophenyl)carbamate, formulators should reach out to established chemical suppliers. Clearly specifying the CAS number (71026-66-9) and required purity is crucial. Requesting quotes and samples allows for thorough evaluation before committing to larger quantities. Suppliers often provide detailed information on packaging, payment terms, and delivery options, facilitating a smooth purchasing process.

By understanding the properties and sourcing channels for tert-Butyl (4-aminophenyl)carbamate, formulation chemists can effectively leverage this intermediate to develop innovative and high-performance products.
