Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 228.25 g/mol gives 2-Phenoxybenzohydrazide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Phenoxybenzohydrazide (CAS 43038-37-5), molecular formula C13H12N2O2 and molecular weight 228.25 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Phenoxybenzohydrazide (C13H12N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 228.25 g/mol, it falls into the medium-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), 2-Phenoxybenzohydrazide 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.
