Chemical Structure

(3R,6R)-2-Hydroxy-6-((1R,3aR,4S,7aR)-4-hydroxy-7a-methyloctahydro-1H-inden-1-yl)-2-methylheptan-3-yl acetate CAS 1243679-36-8 chemical structure

Description

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.

CATO supplies (3R,6R)-2-Hydroxy-6-((1R,3aR,4S,7aR)-4-hydroxy-7a-methyloctahydro-1H-inden-1-yl)-2-methylheptan-3-yl acetate (CAS 1243679-36-8), a certified reference material (molecular formula C20H36O4, MW 340.50 g/mol) for analytical method development and quality control.

The molecular framework of (3R,6R)-2-Hydroxy-6-((1R,3aR,4S,7aR)-4-hydroxy-7a-methyloctahydro-1H-inden-1-yl)-2-methylheptan-3-yl acetate (C20H36O4) is characterized by a carboxylic acid 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. 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.
