Chemical Structure
Description
2-[(E)-(3-Bromo-2-hydroxy-5-methoxyphenyl)methylidene]-1-hydrazinecarbothioamide (CAS 477848-19-4), molecular formula C9H10BrN3O2S and molecular weight 304.16 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-[(E)-(3-Bromo-2-hydroxy-5-methoxyphenyl)methylidene]-1-hydrazinecarbothioamide (C9H10BrN3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 304.16 g/mol, it falls into the moderately-high-molecular-weight range. 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 2-[(E)-(3-Bromo-2-hydroxy-5-methoxyphenyl)methylidene]-1-hydrazinecarbothioamide 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.
