Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1H,2H,3H,9H-Pyrrolo[2,1-b]quinazoline dihydrate hydrochloride (CAS 176040-79-2), a certified reference material (molecular formula C11H12N2HClH2O, MW 226.70 g/mol) for analytical method development and quality control.
1H,2H,3H,9H-Pyrrolo[2,1-b]quinazoline dihydrate hydrochloride (C11H12N2HClH2O) 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, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
CATO manufactures 1H,2H,3H,9H-Pyrrolo[2,1-b]quinazoline dihydrate hydrochloride 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.
