Chemical Structure

4-(3-Chloropropanoyl)-2,3,3a,4-tetrahydropyrrolo[2,1-b]quinazolin-1(9H)-one CAS 6965-13-5 chemical structure

Description

The occurrence of 4-(3-Chloropropanoyl)-2,3,3a,4-tetrahydropyrrolo[2,1-b]quinazolin-1(9H)-one 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-(3-Chloropropanoyl)-2,3,3a,4-tetrahydropyrrolo[2,1-b]quinazolin-1(9H)-one (CAS 6965-13-5) is a high-purity analytical reference standard with the molecular formula C14H15ClN2O2 and a molecular weight of 278.73 g/mol.

4-(3-Chloropropanoyl)-2,3,3a,4-tetrahydropyrrolo[2,1-b]quinazolin-1(9H)-one (C14H15ClN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), 4-(3-Chloropropanoyl)-2,3,3a,4-tetrahydropyrrolo[2,1-b]quinazolin-1(9H)-one 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.
