L-4-Nitrophenylalanine methyl ester hydrochloride, identified by its CAS number 17193-40-7, is a chemical compound of significant interest in various scientific and industrial applications, most notably as a pharmaceutical intermediate. Understanding its intrinsic properties is crucial for researchers and procurement specialists looking to utilize it effectively in synthesis and development projects. As a supplier, we prioritize clarity on these specifications to ensure our clients make informed purchasing decisions.

Chemically, the compound's molecular formula is C10H13ClN2O4, with a molecular weight of approximately 260.67 g/mol. This composition dictates its reactivity and its suitability for specific synthetic transformations. A key characteristic is its appearance: it is typically described as a yellow to off-white or pale yellow solid. This visual identifier is important for quality control upon receipt and during handling.

Regarding its physical behavior, the melting point is a critical parameter. Sources generally report a melting point range between 210°C and 214°C, indicating a degree of thermal stability under moderate conditions. This stability is advantageous for storage and for processes that may involve moderate heating. While detailed solubility data can vary, it is often soluble in common organic solvents used in chemical synthesis, facilitating its integration into reaction mixtures. Proper storage conditions, typically in a cool, dry, and well-closed container, are essential to maintain its integrity and prevent degradation.

The compound is recognized for its high purity, with specifications often reaching ≥98.0% or higher when analyzed by methods such as High-Performance Liquid Chromatography (HPLC). This purity level is particularly vital for its application in pharmaceutical synthesis, where even minor impurities can have significant consequences on the final product's yield, efficacy, and safety profile. Manufacturers that can consistently deliver this level of purity are highly sought after.

In summary, a thorough understanding of L-4-Nitrophenylalanine methyl ester hydrochloride’s properties—from its molecular structure and appearance to its melting point and purity—is fundamental for its successful application. For those looking to buy this essential intermediate, partnering with a knowledgeable supplier that provides detailed technical data is a key step towards efficient research and development.
