Description
CATO manufactures 5-(Benzyloxy)-1H-indole-2-carbohydrazide 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.
5-(Benzyloxy)-1H-indole-2-carbohydrazide (CAS 20948-66-7), molecular formula C16H15N3O2 and molecular weight 281.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(Benzyloxy)-1H-indole-2-carbohydrazide (C16H15N3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.
