ethyl 9-(3,4-dimethyl-5-propylfuran-2-yl)nonanoate CAS CATO-C4X-280621

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including ethyl 9-(3,4-dimethyl-5-propylfuran-2-yl)nonanoate.

ethyl 9-(3,4-dimethyl-5-propylfuran-2-yl)nonanoate (CAS CATO-C4X-280621), molecular formula C20H34O3 and molecular weight 322.48 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of ethyl 9-(3,4-dimethyl-5-propylfuran-2-yl)nonanoate (C20H34O3) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
