Chemical Structure
Description
As a certified reference material (CRM), 2-(hex-1-ynyl)benzoic 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.
2-(hex-1-ynyl)benzoic acid (CAS 120870-47-5), molecular formula C13H14O2 and molecular weight 202.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(hex-1-ynyl)benzoic acid (C13H14O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
