Chemical Structure
Description
As a certified reference material (CRM), Ethyl-2-methyl-4-cyclopropyl-5-pyrimidine 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.
Ethyl-2-methyl-4-cyclopropyl-5-pyrimidine carboxylate (CAS 887410-59-5), molecular formula C11H14N2O2 and molecular weight 206.24 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl-2-methyl-4-cyclopropyl-5-pyrimidine carboxylate (C11H14N2O2) is characterized by an amino-acid-derived structure, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
