Chemical Structure
Description
As a certified reference material (CRM), 3-(4-Chloro-2-methylphenyl)-2-methyl-1-propene 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.
3-(4-Chloro-2-methylphenyl)-2-methyl-1-propene (CAS 951894-06-7), molecular formula C11H13Cl and molecular weight 180.67 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(4-Chloro-2-methylphenyl)-2-methyl-1-propene (C11H13Cl) is characterized by 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
