Chemical Structure
Description
The molecular framework of 2H-1-Benzopyran-7-ol, 3,4-dihydro-3-[(4-hydroxyphenyl)methyl]-, (3R)- (C16H16O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic 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).
2H-1-Benzopyran-7-ol, 3,4-dihydro-3-[(4-hydroxyphenyl)methyl]-, (3R)- (CAS 1180504-64-6) is a high-purity analytical reference standard with the molecular formula C16H16O3 and a molecular weight of 256.30 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2H-1-Benzopyran-7-ol, 3,4-dihydro-3-[(4-hydroxyphenyl)methyl]-, (3R)- under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
