Chemical Structure
Description
Based on its molecular formula C7H7ClN2O3, 2,6-Dimethoxy-4-pyrimidinecarbonyl chloride contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 202.60 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
2,6-Dimethoxy-4-pyrimidinecarbonyl chloride (CAS 52759-24-7), molecular formula C7H7ClN2O3 and molecular weight 202.60 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
