Chemical Structure

2-bromohexadecanoic acid CAS 18263-25-7 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.

2-bromohexadecanoic acid (CAS 18263-25-7), molecular formula C16H31BrO2 and molecular weight 335.32 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, 2-bromohexadecanoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 335.32 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.

As a certified reference material (CRM), 2-bromohexadecanoic 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.
