Chemical Structure
Description
As a certified reference material (CRM), 3,4-Dimethyl-5-propyl-2-furantridecanoic 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.
CATO supplies 3,4-Dimethyl-5-propyl-2-furantridecanoic acid (CAS 69662-69-7), a pharmacopoeial impurity reference standard (molecular formula C22H38O3, MW 350.54 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of 3,4-Dimethyl-5-propyl-2-furantridecanoic acid (C22H38O3) is characterized by a steroid core, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
