Trans-Lamivudine Acid (1R,2S,5R)-5-Methyl-2-isopropylcyclohexyl Ester CAS CATO-C4X-119439

Description

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.

CATO supplies Trans-Lamivudine Acid (1R,2S,5R)-5-Methyl-2-isopropylcyclohexyl Ester (CAS CATO-C4X-119439), a certified reference material (molecular formula C18H27N3O4S, MW 381.49 g/mol) for analytical method development and quality control.

The molecular framework of Trans-Lamivudine Acid (1R,2S,5R)-5-Methyl-2-isopropylcyclohexyl Ester (C18H27N3O4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
