Chemical Structure

(R)-2-Chlorobutyric Acid CAS 54053-45-1 chemical structure

Description

The occurrence of (R)-2-Chlorobutyric Acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (R)-2-Chlorobutyric Acid (CAS 54053-45-1), a certified reference material (molecular formula C4H7ClO2, MW 122.55 g/mol) for analytical method development and quality control.

Based on its molecular formula C4H7ClO2, (R)-2-Chlorobutyric Acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 122.55 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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)-2-Chlorobutyric Acid 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.
