Chemical Structure
Description
As a certified reference material (CRM), Methyl (2S)-2-amino-3-{[(4-methoxyphenyl)methyl]sulfanyl}-3-methylbutanoate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Methyl (2S)-2-amino-3-{[(4-methoxyphenyl)methyl]sulfanyl}-3-methylbutanoate (CAS 1820576-01-9) is a high-purity analytical reference standard with the molecular formula C14H21NO3S and a molecular weight of 283.39 g/mol.
Methyl (2S)-2-amino-3-{[(4-methoxyphenyl)methyl]sulfanyl}-3-methylbutanoate (C14H21NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
