Chemical Structure
Description
CATO supplies Methyl 3-chloro-2-hydroxy-2-methylpropanoate (CAS 54051-05-7), a certified reference material (molecular formula C5H9ClO3, MW 152.58 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 3-chloro-2-hydroxy-2-methylpropanoate (C5H9ClO3) 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.
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), Methyl 3-chloro-2-hydroxy-2-methylpropanoate 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.
