Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 4-((1,1-Dioxido-2h-naphtho[1,8-cd]isothiazol-2-yl)methyl)benzohydrazide (CAS 379254-45-2), a certified reference material (molecular formula C18H15N3O3S, MW 353.40 g/mol) for analytical method development and quality control.
Structurally, 4-((1,1-Dioxido-2h-naphtho[1,8-cd]isothiazol-2-yl)methyl)benzohydrazide (C18H15N3O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 353.40 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.
