N-2-Naphthalenyl-L-leucine CAS 99631-79-5

Description

Compared with other compounds in its class, the molecular weight of 257.33 g/mol gives N-2-Naphthalenyl-L-leucine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N-2-Naphthalenyl-L-leucine (CAS 99631-79-5) is a high-purity analytical reference standard with the molecular formula C16H19NO2 and a molecular weight of 257.33 g/mol.

N-2-Naphthalenyl-L-leucine (C16H19NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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. 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.

As a certified reference material (CRM), N-2-Naphthalenyl-L-leucine 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.
