Chemical Structure
Description
CATO supplies (3Z)-5-Bromo-3-[(4-hydroxyphenyl)imino]-2,3-dihydro-1H-indol-2-one (CAS 57743-19-8), a certified reference material (molecular formula C14H9BrN2O2, MW 317.14 g/mol) for analytical method development and quality control.
Structurally, (3Z)-5-Bromo-3-[(4-hydroxyphenyl)imino]-2,3-dihydro-1H-indol-2-one (C14H9BrN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 317.14 g/mol, it falls into the moderately-high-molecular-weight range. 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), (3Z)-5-Bromo-3-[(4-hydroxyphenyl)imino]-2,3-dihydro-1H-indol-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.
