Chemical Structure
Description
5-Tert-butyl-4,5,6,7-tetrahydro-1-benzothiophene-2-carbohydrazide (CAS 749906-98-7) is a high-purity analytical reference standard with the molecular formula C13H20N2OS and a molecular weight of 252.38 g/mol.
The molecular framework of 5-Tert-butyl-4,5,6,7-tetrahydro-1-benzothiophene-2-carbohydrazide (C13H20N2OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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 5-Tert-butyl-4,5,6,7-tetrahydro-1-benzothiophene-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.
