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.
4-(Phenyl-d5)-2-butenone 4-(Phenyl-d5)-3-buten-2-one 56187-93-0 Acetocinnamone-d5 Benzalacetone-d5 Benzylideneacetone-d5 Methyl 2-(Phenyl-d5)vinyl Ketone Methyl Styryl Ketone-d5 NSC 5605-d5 (CAS 56187-93-0), molecular formula C10H5D5O and molecular weight 151.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(Phenyl-d5)-2-butenone 4-(Phenyl-d5)-3-buten-2-one 56187-93-0 Acetocinnamone-d5 Benzalacetone-d5 Benzylideneacetone-d5 Methyl 2-(Phenyl-d5)vinyl Ketone Methyl Styryl Ketone-d5 NSC 5605-d5 (C10H5D5O) is characterized by deuterium isotope labeling, 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), 4-(Phenyl-d5)-2-butenone 4-(Phenyl-d5)-3-buten-2-one 56187-93-0 Acetocinnamone-d5 Benzalacetone-d5 Benzylideneacetone-d5 Methyl 2-(Phenyl-d5)vinyl Ketone Methyl Styryl Ketone-d5 NSC 5605-d5 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.
