Chemical Structure

6,7-Dimethoxy-3-methyl-5-propyl-3,4-dihydronaphthalen-1(2H)-one CAS 213971-37-0 chemical structure

Description

The occurrence of 6,7-Dimethoxy-3-methyl-5-propyl-3,4-dihydronaphthalen-1(2H)-one is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 6,7-Dimethoxy-3-methyl-5-propyl-3,4-dihydronaphthalen-1(2H)-one (CAS 213971-37-0), a certified reference material (molecular formula C16H22O3, MW 262.34 g/mol) for analytical method development and quality control.

Structurally, 6,7-Dimethoxy-3-methyl-5-propyl-3,4-dihydronaphthalen-1(2H)-one (C16H22O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 262.34 g/mol, it falls into the medium-molecular-weight range. 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).

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), 6,7-Dimethoxy-3-methyl-5-propyl-3,4-dihydronaphthalen-1(2H)-one 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.
