Chemical Structure

(2S)-Piperazine-2-carboxylic acid, N1-FMOC protected hydrochloride hemihydrate CAS 915707-72-1 chemical structure

Description

The occurrence of (2S)-Piperazine-2-carboxylic acid, N1-FMOC protected hydrochloride hemihydrate is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (2S)-Piperazine-2-carboxylic acid, N1-FMOC protected hydrochloride hemihydrate (CAS 915707-72-1), a certified reference material (molecular formula C20H20N2O4HClH2O, MW 406.86 g/mol) for analytical method development and quality control.

Based on its molecular formula C20H20N2O4HClH2O, (2S)-Piperazine-2-carboxylic acid, N1-FMOC protected hydrochloride hemihydrate contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 406.86 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
