For scientists and researchers in the pharmaceutical, biochemical, and materials science fields, the quality of chemical intermediates is non-negotiable. 3-(4-Hydroxyphenyl)propionic acid (CAS 501-97-3), also known as phloretic acid, is a valuable compound used in various research applications, including its role as a sensitive substrate for enzymes and a building block in organic synthesis. When looking to buy 3-(4-hydroxyphenyl)propionic acid for research, understanding its key specifications is vital.

Critical Quality Parameters for Researchers

When procuring chemicals for R&D, adherence to precise specifications ensures the accuracy and reproducibility of experiments. For 3-(4-Hydroxyphenyl)propionic acid, the critical parameters typically include:

• Assay/Purity: The most important specification is the purity level, commonly stated as an assay percentage. For most research applications, a purity of ≥98.0% is considered standard, with 99% purity often preferred for more sensitive analyses or complex synthesis pathways. Ensuring you buy high purity 3-(4-hydroxyphenyl)propionic acid is paramount.
• Appearance: The typical appearance is an off-white to beige powder or granules. Significant deviations in color or form may indicate impurities or degradation.
• Melting Point: A sharp melting point within the specified range (129-131 °C) is indicative of high purity. Variations can suggest the presence of isomers or other contaminants.
• Solubility: Understanding its solubility in common research solvents (e.g., DMSO, methanol, hot water) is essential for experimental design and execution.

Reliable Sourcing for R&D Needs

Researchers often need to purchase phloretic acid in smaller quantities for initial studies or in larger batches for ongoing projects. To ensure a consistent supply of high-quality material:

• Partner with Trusted Suppliers: Identify a reputable manufacturer or supplier of 3-(4-hydroxyphenyl)propionic acid who can provide detailed Certificates of Analysis (CoA) for each batch. This documentation is crucial for validating the material's quality.
• Check Manufacturer's Expertise: Companies specializing in fine chemicals and pharmaceutical intermediates often have a deeper understanding of the requirements for R&D applications.
• Consider Packaging: While commonly supplied in 25kg drums for industrial use, inquire about smaller R&D-sized packaging options if needed.

For research institutions and laboratories requiring a dependable source of CAS 501-97-3, prioritizing quality specifications and a reliable supply chain is essential. Choosing a supplier that can consistently deliver material meeting stringent purity requirements will directly impact the success of your research endeavors.
