Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 247.10 g/mol gives BT2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
BT2 (CAS 34576-94-8), molecular formula C9H4Cl2O2S and molecular weight 247.10 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H4Cl2O2S, BT2 contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 247.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 BT2 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.
