Researchers and development scientists often require detailed technical specifications for chemical intermediates to ensure successful and reproducible experimental outcomes. (S)-Ethyl 2-Hydroxy-4-phenylbutanoate, CAS 125639-64-7, is a prime example of such a compound, frequently sought after for its role in organic synthesis. Understanding its precise properties is crucial for formulators and synthetic chemists when they plan to buy or use this material. Reputable manufacturers provide comprehensive data, enabling informed decision-making in laboratory settings and pilot-scale production.

Key technical parameters for (S)-Ethyl 2-Hydroxy-4-phenylbutanoate typically include its appearance, specified as a pale yellow to dark yellow oil. Its molecular formula is C12H16O3, with a molecular weight of approximately 208.25. Purity is a critical specification, commonly cited as ≥98% or sometimes ≥95% depending on the grade. Physical properties such as density (around 1.075 g/mL at 20 °C), refractive index (n20/D 1.505), and flash point (approximately 150 °C) are also vital for safe handling and process design. Solubility in common organic solvents like chloroform and methanol further defines its application scope.

For R&D purposes, ensuring the enantiomeric purity of (S)-Ethyl 2-Hydroxy-4-phenylbutanoate is often as important as its chemical purity. While not always explicitly stated in general product descriptions, specialized suppliers might offer information on specific rotation or enantiomeric excess. When procuring this chemical, requesting a detailed Certificate of Analysis (CoA) from the manufacturer is standard practice. This document will confirm the batch-specific purity and other relevant analytical data, providing assurance for research projects. Reliable suppliers in China, like many fine chemical manufacturers, are equipped to provide these critical technical details, supporting the advancement of chemical research and development.
