Description
As a certified reference material (CRM), Ethyl Hexadecanoate-d31 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.
Ethyl Hexadecanoate-d31 (CAS 1215721-57-5), molecular formula C18H5D31O2 and molecular weight 315.67 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Ethyl Hexadecanoate-d31 (C18H5D31O2) contains deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 16.5, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 315.67 g/mol, it falls into the moderately-high-molecular-weight range. 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.
