Description
CATO manufactures 4,6-Dichloro-2h-thiochromene-3-carbaldehyde 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.
4,6-Dichloro-2h-thiochromene-3-carbaldehyde (CAS 54949-15-4) is a high-purity analytical reference standard with the molecular formula C10H6Cl2OS and a molecular weight of 245.13 g/mol.
The molecular framework of 4,6-Dichloro-2h-thiochromene-3-carbaldehyde (C10H6Cl2OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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 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.
