Chemical Structure
Description
(3-Chloro-4-methylphenyl)(hydroxy)(thiophen-3-yl)borane (CAS 873101-39-4), molecular formula C11H10BClOS and molecular weight 236.53 g/mol, is a CATO reference standard with documented purity and traceability.
(3-Chloro-4-methylphenyl)(hydroxy)(thiophen-3-yl)borane (C11H10BClOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), (3-Chloro-4-methylphenyl)(hydroxy)(thiophen-3-yl)borane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
