Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 170.64 g/mol gives 2-Chloro-4-isopropylphenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Chloro-4-isopropylphenol (CAS 51202-00-7), molecular formula C9H11ClO and molecular weight 170.64 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Chloro-4-isopropylphenol (C9H11ClO) is characterized by a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 2-Chloro-4-isopropylphenol 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.
