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.
CATO supplies 1,3-diethyl 2-undecylidenepropanedioate 1314006-44-4 KS-00002WTN (CAS 1314006-44-4), a certified reference material (molecular formula C18H32O4, MW 312.44 g/mol) for analytical method development and quality control.
Structurally, 1,3-diethyl 2-undecylidenepropanedioate 1314006-44-4 KS-00002WTN (C18H32O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 312.44 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.
As a certified reference material (CRM), 1,3-diethyl 2-undecylidenepropanedioate 1314006-44-4 KS-00002WTN 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.
