Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 8-Methoxy-3-methyl-1H-isochromen-1-one.
8-Methoxy-3-methyl-1H-isochromen-1-one (CAS 830-54-6) is a high-purity analytical reference standard with the molecular formula C11H10O3 and a molecular weight of 190.20 g/mol.
The molecular framework of 8-Methoxy-3-methyl-1H-isochromen-1-one (C11H10O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 8-Methoxy-3-methyl-1H-isochromen-1-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.
