Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 658-48-0 X88TTO174Z alpha-Methyltyrosine Metyrosine, DL- Racemetirosine [INN] Racemetirosine Racemetyrosine [USAN] DL-alpha-Methyltyrosine Tyrosine, alpha-methyl- H 9/88 4-14-00-02453 (Beilstein Handbook Reference) AI3-62542 BRN 2938704 EINECS 210-635-7 EINECS 211-523-0 alpha-Methylparatyrosine, DL- alpha-Methyl-p-tyrosine Racemetirosina [INN-Spanish] Racemetirosinum [INN-Latin] (R,S)-2-Amino-3-(4-hydroxyphenyl)-2-methylpropionsaeure (+-)-alpha-Methyl-DL-tyrosine Racemetirosina Racemetirosinum UNII-X88TTO174Z Racemetyrosine SM-88 WHO 4292 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 201.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
