Chemical Structure

3-Chlorobutyric Acid CAS 1951-12-8 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 3-Chlorobutyric Acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 122.55 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

3-Chlorobutyric Acid (CAS 1951-12-8), molecular formula C4H7ClO2 and molecular weight 122.55 g/mol, is a CATO reference standard with documented purity and traceability.

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-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.
