Chemical Structure
Description
2-Chlorobenzaldehyde-D4 (CAS 1093351-46-2) is a high-purity analytical reference standard with the molecular formula C7HD4ClO and a molecular weight of 144.59 g/mol.
2-Chlorobenzaldehyde-D4 (C7HD4ClO) contains deuterium isotope labeling, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 2-Chlorobenzaldehyde-D4 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.
