(5-Amino-1-ethyl-1H-pyrazol-3-yl)(piperidin-1-yl)methanone CAS 1856033-37-8

Description

As a certified reference material (CRM), (5-Amino-1-ethyl-1H-pyrazol-3-yl)(piperidin-1-yl)methanone 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.

(5-Amino-1-ethyl-1H-pyrazol-3-yl)(piperidin-1-yl)methanone (CAS 1856033-37-8), molecular formula C11H18N4O and molecular weight 222.29 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (5-Amino-1-ethyl-1H-pyrazol-3-yl)(piperidin-1-yl)methanone (C11H18N4O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
