Compared with other compounds in its class, the molecular weight of 232.23 g/mol gives 2-(((2-Methylbut-3-yn-2-yl)oxy)carbonyl)benzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-(((2-Methylbut-3-yn-2-yl)oxy)carbonyl)benzoic acid (CAS 296881-56-6), a certified reference material (molecular formula C13H12O4, MW 232.23 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 2-(((2-Methylbut-3-yn-2-yl)oxy)carbonyl)benzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 232.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
CATO manufactures 2-(((2-Methylbut-3-yn-2-yl)oxy)carbonyl)benzoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
