Chemical Structure
Description
CATO supplies (4-Chloro-3,5-dimethylphenyl)methanol (CAS 18982-59-7), a certified reference material (molecular formula C9H11ClO, MW 170.64 g/mol) for analytical method development and quality control.
(4-Chloro-3,5-dimethylphenyl)methanol (C9H11ClO) contains a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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), (4-Chloro-3,5-dimethylphenyl)methanol 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.
