Chemical Structure
Description
The occurrence of 4-Chloro-6-(1-ethoxyvinyl)pyrimidine is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Chloro-6-(1-ethoxyvinyl)pyrimidine (CAS 736991-92-7) is a high-purity analytical reference standard with the molecular formula C8H9ClN2O and a molecular weight of 184.62 g/mol.
4-Chloro-6-(1-ethoxyvinyl)pyrimidine (C8H9ClN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 4-Chloro-6-(1-ethoxyvinyl)pyrimidine 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.
