(R)-Ethyl 2-chloropropanoate CAS 42411-39-2

Description

Compared with other compounds in its class, the molecular weight of 136.58 g/mol gives (R)-Ethyl 2-chloropropanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(R)-Ethyl 2-chloropropanoate (CAS 42411-39-2) is a high-purity analytical reference standard with the molecular formula C5H9ClO2 and a molecular weight of 136.58 g/mol.

The molecular framework of (R)-Ethyl 2-chloropropanoate (C5H9ClO2) 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), (R)-Ethyl 2-chloropropanoate 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.
