Chemical Structure
Description
The occurrence of 3-Allyl-7-hydroxy-4-methyl-2H-chromen-2-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.
3-Allyl-7-hydroxy-4-methyl-2H-chromen-2-one (CAS 26481-13-0) is a high-purity analytical reference standard with the molecular formula C13H12O3 and a molecular weight of 216.23 g/mol.
The molecular framework of 3-Allyl-7-hydroxy-4-methyl-2H-chromen-2-one (C13H12O3) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 3-Allyl-7-hydroxy-4-methyl-2H-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.
