Chemical Structure

2H-Thiochromene CAS 254-37-5 chemical structure

Description

CATO manufactures 2H-Thiochromene 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.

2H-Thiochromene (CAS 254-37-5), molecular formula C9H8S and molecular weight 148.22 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2H-Thiochromene (C9H8S) contains sulfur-containing functionality, an aromatic ring system. 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 148.22 g/mol, it falls into the low-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
