Chemical Structure
Description
As a certified reference material (CRM), 5-(3-Butylphenyl)-N-cyclopentyl-2-methylpyrimidin-4-amine 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.
CATO supplies 5-(3-Butylphenyl)-N-cyclopentyl-2-methylpyrimidin-4-amine (CAS 917895-79-5), a certified reference material (molecular formula C20H27N3, MW 309.45 g/mol) for analytical method development and quality control.
Structurally, 5-(3-Butylphenyl)-N-cyclopentyl-2-methylpyrimidin-4-amine (C20H27N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 309.45 g/mol, it falls into the moderately-high-molecular-weight range. 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.
