Chemical Structure

4-Methyl-N-(4-methyl-2-oxo-6-phenyl-2H-pyran-3-yl)benzamide CAS 478067-13-9 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 4-Methyl-N-(4-methyl-2-oxo-6-phenyl-2H-pyran-3-yl)benzamide.

CATO supplies 4-Methyl-N-(4-methyl-2-oxo-6-phenyl-2H-pyran-3-yl)benzamide (CAS 478067-13-9), a certified reference material (molecular formula C20H17NO3, MW 319.35 g/mol) for analytical method development and quality control.

4-Methyl-N-(4-methyl-2-oxo-6-phenyl-2H-pyran-3-yl)benzamide (C20H17NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. 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.

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 4-Methyl-N-(4-methyl-2-oxo-6-phenyl-2H-pyran-3-yl)benzamide 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.
