In the realm of chemical synthesis, particularly in the pharmaceutical and advanced materials sectors, the strategic use of well-defined intermediates can dramatically improve efficiency, purity, and yield. [1,1':4',1''-Terphenyl]-4-carboxylic acid, 4''-(pentyloxy)-, identified by its CAS number 158938-08-0, exemplifies the value of such specialized building blocks.

This compound, with its characteristic terphenyl core, a carboxylic acid functional group, and a pentyloxy substituent, offers a unique combination of structural features. Its molecular formula is C24H24O3, and it has a molecular weight of 360.45. As a white to off-white solid, it presents a stable form for handling and processing in various synthetic routes. The carboxylic acid group is particularly valuable, serving as a versatile anchor point for further chemical modifications, such as esterifications, amidations, or couplings.

The primary application driving demand for this specific terphenyl carboxylic acid derivative is its critical role in the synthesis of Anidulafungin. Anidulafungin is a crucial antifungal agent, and the precise molecular architecture provided by CAS 158938-08-0 is essential for its effective biological activity. By incorporating this intermediate, synthetic chemists can efficiently assemble the complex structure of the API, often leading to higher yields and a more controlled reaction pathway compared to building the entire structure from simpler precursors.

Beyond its pharmaceutical application, the rigid, extended aromatic system inherent in terphenyl structures suggests potential utility in materials science, for instance, in the development of advanced polymers or liquid crystalline materials. However, for the immediate market, its significance as a pharmaceutical intermediate remains paramount. When sourcing this compound, chemists and procurement specialists look for high purity (typically ≥99%) to ensure the success of subsequent synthetic steps and the quality of the final product.

Reliable suppliers, often based in China, offer this crucial intermediate, enabling researchers and manufacturers to optimize their synthesis strategies. By providing well-characterized intermediates like [1,1':4',1''-Terphenyl]-4-carboxylic acid, 4''-(pentyloxy)-, chemical manufacturers facilitate innovation and production, allowing the scientific community to focus on downstream development and application. If you are looking to buy this high-quality intermediate for your synthesis needs, consider partnering with experienced suppliers who understand the demands of advanced chemical manufacturing.
