Description

Compared with other compounds in its class, the molecular weight of 476.96 g/mol gives tert-Butyl 4-[6-(4-chlorophenyl)-5-cyano-2-(pyridin-4-yl)pyrimidin-4-yl]piperazine-1-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

tert-Butyl 4-[6-(4-chlorophenyl)-5-cyano-2-(pyridin-4-yl)pyrimidin-4-yl]piperazine-1-carboxylate (CAS 383148-76-3), molecular formula C25H25ClN6O2 and molecular weight 476.96 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of tert-Butyl 4-[6-(4-chlorophenyl)-5-cyano-2-(pyridin-4-yl)pyrimidin-4-yl]piperazine-1-carboxylate (C25H25ClN6O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.

As a certified reference material (CRM), tert-Butyl 4-[6-(4-chlorophenyl)-5-cyano-2-(pyridin-4-yl)pyrimidin-4-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.
