(S)-tert-Butyl 2-(tert-butyl)piperazine-1-carboxylate hydrochloride CAS 1381959-73-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-tert-Butyl 2-(tert-butyl)piperazine-1-carboxylate hydrochloride.

(S)-tert-Butyl 2-(tert-butyl)piperazine-1-carboxylate hydrochloride (CAS 1381959-73-4), molecular formula C13H26N2O2HCl and molecular weight 278.82 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, (S)-tert-Butyl 2-(tert-butyl)piperazine-1-carboxylate hydrochloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 278.82 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
