Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,8-Dichloro-2-isopropylquinazoline.
CATO supplies 4,8-Dichloro-2-isopropylquinazoline (CAS 887590-80-9), a certified reference material (molecular formula C11H10Cl2N2, MW 241.12 g/mol) for analytical method development and quality control.
Based on its molecular formula C11H10Cl2N2, 4,8-Dichloro-2-isopropylquinazoline contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 241.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4,8-Dichloro-2-isopropylquinazoline under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
