Chemical Structure
Description
As a certified reference material (CRM), (4-Heptylphenyl)(4-methylpyridin-2-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.
(4-Heptylphenyl)(4-methylpyridin-2-yl)methanone (CAS 1187165-20-3) is a high-purity analytical reference standard with the molecular formula C20H25NO and a molecular weight of 295.42 g/mol.
The molecular framework of (4-Heptylphenyl)(4-methylpyridin-2-yl)methanone (C20H25NO) is characterized by a steroid core, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
