2H-1-benzopyran-2-one, 8-acetyl-7-hydroxy- 6748-68-1 8 - Acetyl - 7 - hydroxycoumarin 8-Acetyl-7-hydroxy-2H-chromen-2-one 8-acetyl-7-hydroxy-chromen-2-one CAS 6748-68-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2H-1-benzopyran-2-one, 8-acetyl-7-hydroxy- 6748-68-1 8 - Acetyl - 7 - hydroxycoumarin 8-Acetyl-7-hydroxy-2H-chromen-2-one 8-acetyl-7-hydroxy-chromen-2-one.

2H-1-benzopyran-2-one, 8-acetyl-7-hydroxy- 6748-68-1 8 - Acetyl - 7 - hydroxycoumarin 8-Acetyl-7-hydroxy-2H-chromen-2-one 8-acetyl-7-hydroxy-chromen-2-one (CAS 6748-68-1) is a high-purity analytical reference standard with the molecular formula C11H14O4 and a molecular weight of 210.23 g/mol.

2H-1-benzopyran-2-one, 8-acetyl-7-hydroxy- 6748-68-1 8 - Acetyl - 7 - hydroxycoumarin 8-Acetyl-7-hydroxy-2H-chromen-2-one 8-acetyl-7-hydroxy-chromen-2-one (C11H14O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 2H-1-benzopyran-2-one, 8-acetyl-7-hydroxy- 6748-68-1 8 - Acetyl - 7 - hydroxycoumarin 8-Acetyl-7-hydroxy-2H-chromen-2-one 8-acetyl-7-hydroxy-chromen-2-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.
