Chemical Structure
Description
(E)-3-(3,5-Di-tert-butyl-4-hydroxyphenyl)acrylic Acid (CAS 95602-92-9) is a high-purity analytical reference standard with the molecular formula C17H24O3 and a molecular weight of 276.37 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, (E)-3-(3,5-Di-tert-butyl-4-hydroxyphenyl)acrylic Acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 276.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), (E)-3-(3,5-Di-tert-butyl-4-hydroxyphenyl)acrylic 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.
