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.
2,2,5-Trimethyl-1,3-dioxane-5-carboxylic Acid Vinyl Ester-d3 (CAS 1185176-80-0) is a high-purity analytical reference standard with the molecular formula C10H13D3O4 and a molecular weight of 203.25 g/mol.
The molecular framework of 2,2,5-Trimethyl-1,3-dioxane-5-carboxylic Acid Vinyl Ester-d3 (C10H13D3O4) is characterized by deuterium isotope labeling, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 2,2,5-Trimethyl-1,3-dioxane-5-carboxylic Acid Vinyl Ester-d3 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.
