3-Ethyl-4,5-dimethoxy-1-methyl-1,3-dihydroisobenzofuran CAS 688005-06-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Ethyl-4,5-dimethoxy-1-methyl-1,3-dihydroisobenzofuran.

3-Ethyl-4,5-dimethoxy-1-methyl-1,3-dihydroisobenzofuran (CAS 688005-06-3) is a high-purity analytical reference standard with the molecular formula C13H18O3 and a molecular weight of 222.28 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 3-Ethyl-4,5-dimethoxy-1-methyl-1,3-dihydroisobenzofuran is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 222.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 3-Ethyl-4,5-dimethoxy-1-methyl-1,3-dihydroisobenzofuran 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.
