Chemical Structure
Description
methyl 2-azido-3-(4,5-dichloro-2-methoxy-phenyl)prop-2-enoate (CAS 2755783-40-3) is a high-purity analytical reference standard with the molecular formula C11H15Cl2N3O3 and a molecular weight of 308.16 g/mol.
methyl 2-azido-3-(4,5-dichloro-2-methoxy-phenyl)prop-2-enoate (C11H15Cl2N3O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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), methyl 2-azido-3-(4,5-dichloro-2-methoxy-phenyl)prop-2-enoate 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.
