Chemical Structure

3-Chloro-2-methylpropane-1,2-diol CAS 597-33-1 chemical structure

Description

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.

3-Chloro-2-methylpropane-1,2-diol (CAS 597-33-1), molecular formula C4H9ClO2 and molecular weight 124.57 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-Chloro-2-methylpropane-1,2-diol (C4H9ClO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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.

As a certified reference material (CRM), 3-Chloro-2-methylpropane-1,2-diol 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.
