Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Chloro-2,4-dimethylbenzyl alcohol.
3-Chloro-2,4-dimethylbenzyl alcohol (CAS 1780815-77-1), molecular formula C9H11ClO and molecular weight 170.64 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H11ClO, 3-Chloro-2,4-dimethylbenzyl alcohol contains 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 170.64 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-2,4-dimethylbenzyl alcohol 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.
