Compared with other compounds in its class, the molecular weight of 265.22 g/mol gives Salicylaldoxime distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Salicylaldoxime (CAS 129-56-6), molecular formula C8H15N3O7 and molecular weight 265.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Salicylaldoxime (C8H15N3O7) is characterized by a carbohydrate-derived structure, an amide group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures Salicylaldoxime 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.
