Chemical compounds are often identified and referenced by their unique CAS (Chemical Abstracts Service) numbers, which serve as globally recognized identifiers. For researchers and procurement professionals in the chemical and pharmaceutical industries, understanding the applications and sourcing of key compounds like CAS 511272-46-1 is fundamental to successful project execution. This number specifically refers to Fmoc-(R)-3-Amino-3-(3-thienyl)-propionic acid, a vital chiral building block.

Fmoc-(R)-3-Amino-3-(3-thienyl)-propionic acid (CAS 511272-46-1) is highly valued in advanced organic synthesis, particularly for its role in peptide chemistry. The presence of the Fmoc protecting group makes it a convenient and effective reagent for solid-phase peptide synthesis (SPPS), a cornerstone technique in drug discovery and development. This protection strategy allows for sequential addition of amino acids in a controlled manner. For any research institution or company looking to buy this compound, ensuring its CAS number is correctly listed and that the product meets high purity standards is crucial. It is important to find a reputable supplier that can provide this assurance.

The compound's structure, featuring a thiophene ring attached to a chiral propionic acid backbone, provides unique chemical properties that can be exploited in various applications. Thiophene moieties are often incorporated into molecules to modify their electronic characteristics, solubility, or interaction with biological targets. This makes Fmoc-(R)-3-Amino-3-(3-thienyl)-propionic acid particularly useful in medicinal chemistry for developing novel drug candidates. Researchers aiming to synthesize peptides with enhanced biological activity or stability often turn to such specialized amino acid derivatives. The price of such advanced intermediates can vary, so understanding market value from different suppliers is beneficial.

When procuring chemicals for research and development, particularly those with specific stereochemistry and functional groups, sourcing from a reliable manufacturer in China or elsewhere is essential. A trustworthy supplier not only provides the correct chemical entity (identified by its CAS number) but also guarantees its quality, purity, and consistency. This reliability is critical for reproducible scientific results and the efficient progression of R&D projects. Accessing comprehensive technical data, such as Certificates of Analysis, from your supplier further bolsters confidence in the material.

In summary, CAS 511272-46-1, or Fmoc-(R)-3-Amino-3-(3-thienyl)-propionic acid, is a significant compound in modern chemical synthesis. Its specific properties make it indispensable for advanced peptide construction and drug discovery efforts. By partnering with experienced chemical manufacturers and suppliers who can accurately provide this CAS-identified compound, research and development teams can secure the high-quality materials necessary to drive innovation.
