16135-41-4 6,7-dimethoxy-1,4-dihydroisochromen-3-one 6,7-dimethoxy-3,4-dihydro-1H-2-benzopyran-3-one A810255 CAS 16135-41-4 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 16135-41-4 6,7-dimethoxy-1,4-dihydroisochromen-3-one 6,7-dimethoxy-3,4-dihydro-1H-2-benzopyran-3-one A810255.

16135-41-4 6,7-dimethoxy-1,4-dihydroisochromen-3-one 6,7-dimethoxy-3,4-dihydro-1H-2-benzopyran-3-one A810255 (CAS 16135-41-4) is a high-purity analytical reference standard with the molecular formula C11H12O4 and a molecular weight of 208.21 g/mol.

The molecular framework of 16135-41-4 6,7-dimethoxy-1,4-dihydroisochromen-3-one 6,7-dimethoxy-3,4-dihydro-1H-2-benzopyran-3-one A810255 (C11H12O4) 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 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.
