Chemical Structure
Description
Ethyl 3-amino-4-(1-piperidinyl)benzoate (CAS 71254-74-5), molecular formula C14H20N2O2 and molecular weight 248.32 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 3-amino-4-(1-piperidinyl)benzoate (C14H20N2O2) 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 its high hydrophobicity (logP), 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), Ethyl 3-amino-4-(1-piperidinyl)benzoate 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.
