28020-73-7 AR-1L1936 propan-2-yl 4-(2-{pentyl[(propan-2-yloxy)carbonyl]amino}ethyl)piperazine-1-carboxylate hydrochloride(1:1) CAS 28020-73-7

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.

28020-73-7 AR-1L1936 propan-2-yl 4-(2-{pentyl[(propan-2-yloxy)carbonyl]amino}ethyl)piperazine-1-carboxylate hydrochloride(1:1) (CAS 28020-73-7) is a high-purity analytical reference standard with the molecular formula C19H35N5 and a molecular weight of 333.51 g/mol.

The molecular framework of 28020-73-7 AR-1L1936 propan-2-yl 4-(2-{pentyl[(propan-2-yloxy)carbonyl]amino}ethyl)piperazine-1-carboxylate hydrochloride(1:1) (C19H35N5) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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. 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.
