Description
CATO manufactures 3,4-Dimethyl-5-pentyl-2-furannonanoic Acid Methyl Ester under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 3,4-Dimethyl-5-pentyl-2-furannonanoic Acid Methyl Ester (CAS 81144-79-8), a certified reference material (molecular formula C21H36O3, MW 336.51 g/mol) for analytical method development and quality control.
Owing to a steroid core, a hydroxyl group, an ether linkage, 3,4-Dimethyl-5-pentyl-2-furannonanoic Acid Methyl Ester is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 336.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
