In the realm of organic chemistry, certain compounds serve as foundational building blocks for more complex molecules. 4-(Hydroxymethyl)phenoxyacetic acid, identified by its CAS number 68858-21-9, is one such critical intermediate. While often referred to by its shorthand 'HMP Linker,' understanding its properties and applications is key for procurement managers and R&D scientists looking to source high-quality chemical raw materials.

This versatile compound is characterized by its off-white crystalline powder appearance and its crucial role as a linkage agent. Its primary application lies in solid-phase peptide synthesis, specifically within the FMOC-polyamide technique. Here, it acts as the crucial connection point between the solid resin support and the growing peptide chain, enabling the precise and sequential assembly of amino acids.

For those in the market to buy 4-(Hydroxymethyl)phenoxyacetic acid, recognizing its CAS number (68858-21-9) is the first step in efficient sourcing. This identifier is vital for accurately communicating product needs to manufacturers and suppliers worldwide. When searching for '4-(Hydroxymethyl)phenoxyacetic acid supplier' or 'HMP Linker manufacturer,' this CAS number will ensure you find the precise chemical you require.

The purity of this building block is paramount. High-purity grades, often specified as 98% or higher, are essential to prevent unintended side reactions and ensure the integrity of the synthesized peptides. This is particularly important in pharmaceutical applications, where stringent quality standards are non-negotiable. Therefore, when evaluating potential suppliers, always inquire about the purity levels and request available analytical data such as HPLC or NMR reports.

Manufacturers specializing in fine chemicals and pharmaceutical intermediates, such as NINGBO INNO PHARMCHEM CO.,LTD., are key sources for this compound. Their ability to produce and supply 4-(Hydroxymethyl)phenoxyacetic acid in bulk, coupled with competitive pricing, makes them valuable partners for research institutions and production facilities. Engaging directly with such manufacturers can streamline the procurement process and ensure a reliable supply for ongoing projects.

In conclusion, 4-(Hydroxymethyl)phenoxyacetic acid (CAS 68858-21-9) is more than just a chemical intermediate; it is a critical enabler of advanced synthesis. By understanding its properties, applications, and the importance of sourcing from reputable manufacturers, procurement professionals can effectively secure this essential building block for their critical research and development initiatives.
