Chemical Structure

Methyl 2-isothiocyanato-5,6,7,8-tetrahydro-4H-cyclohepta[b]thiophene-3-carboxylate CAS 588695-57-2 chemical structure

Description

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.

Methyl 2-isothiocyanato-5,6,7,8-tetrahydro-4H-cyclohepta[b]thiophene-3-carboxylate (CAS 588695-57-2), molecular formula C12H13NO2S2 and molecular weight 267.37 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Methyl 2-isothiocyanato-5,6,7,8-tetrahydro-4H-cyclohepta[b]thiophene-3-carboxylate (C12H13NO2S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO manufactures Methyl 2-isothiocyanato-5,6,7,8-tetrahydro-4H-cyclohepta[b]thiophene-3-carboxylate 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.
