Chemical Structure
Description
CATO supplies 7-Chloro-4-[(4-ethylphenyl)methyl]-2,3,4,5-tetrahydro-1,4-benzoxazepin-3-one (CAS 1326909-70-9), a certified reference material (molecular formula C18H18ClNO2, MW 315.79 g/mol) for analytical method development and quality control.
7-Chloro-4-[(4-ethylphenyl)methyl]-2,3,4,5-tetrahydro-1,4-benzoxazepin-3-one (C18H18ClNO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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.
As a certified reference material (CRM), 7-Chloro-4-[(4-ethylphenyl)methyl]-2,3,4,5-tetrahydro-1,4-benzoxazepin-3-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.
