Chemical Structure
Description
The molecular framework of C 75 (4-Methylene-2-octyl-5-oxo-tetrahydro-furan-3-carboxylic acid) (C14H22O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
C 75 (4-Methylene-2-octyl-5-oxo-tetrahydro-furan-3-carboxylic acid) (CAS 218137-86-1) is a high-purity analytical reference standard with the molecular formula C14H22O4 and a molecular weight of 254.32 g/mol.
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), C 75 (4-Methylene-2-octyl-5-oxo-tetrahydro-furan-3-carboxylic acid) 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.
