Chemical Structure

tert-Butyl 4-(6-chloropyrazin-2-yl)piperazine-1-carboxylate CAS 426829-52-9 chemical structure

Description

The occurrence of tert-Butyl 4-(6-chloropyrazin-2-yl)piperazine-1-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

tert-Butyl 4-(6-chloropyrazin-2-yl)piperazine-1-carboxylate (CAS 426829-52-9) is a high-purity analytical reference standard with the molecular formula C13H19ClN4O2 and a molecular weight of 298.77 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, tert-Butyl 4-(6-chloropyrazin-2-yl)piperazine-1-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 298.77 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), tert-Butyl 4-(6-chloropyrazin-2-yl)piperazine-1-carboxylate 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.
