Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Amino-4-(3-methoxyphenyl)-4h-benzo[h]chromene-3-carbonitrile (CAS 149550-57-2) is a high-purity analytical reference standard with the molecular formula C21H16N2O2 and a molecular weight of 328.36 g/mol.
The molecular framework of 2-Amino-4-(3-methoxyphenyl)-4h-benzo[h]chromene-3-carbonitrile (C21H16N2O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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.
CATO manufactures 2-Amino-4-(3-methoxyphenyl)-4h-benzo[h]chromene-3-carbonitrile 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.
