Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(2,4-Dichlorophenoxy)-3-methylisoxazolo[5,4-d]pyrimidine.
4-(2,4-Dichlorophenoxy)-3-methylisoxazolo[5,4-d]pyrimidine (CAS 672925-29-0) is a high-purity analytical reference standard with the molecular formula C12H7Cl2N3O2 and a molecular weight of 296.11 g/mol.
The molecular framework of 4-(2,4-Dichlorophenoxy)-3-methylisoxazolo[5,4-d]pyrimidine (C12H7Cl2N3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
