4-Chloro-2-cyclopropylquinazoline

4-Chloro-2-cyclopropylquinazoline identifies CAS 898044-61-6 and molecular formula C11H9ClN2. A CAS search in PubChem returns one entry, CID 42809123, with the same compound title. The Rlavie name occurs in PubChem’s official synonym collection, connecting the page to that single record. The chlorine and cyclopropyl locants therefore belong with the CAS rather than serving as optional wording in a shortened quinazoline label.

Verified SMILES C1CC1C2=NC3=CC=CC=C3C(=N2)Cl shows a three-membered cyclopropyl ring attached to the fused quinazoline system. The terminal chlorine is connected at the carbon identified by position 4. PubChem reports InChIKey IQBRXDZPRMYVCR-UHFFFAOYSA-N, which agrees with the full InChI recorded on the page. Together, these notations preserve the fused-ring connections and separate the entry from a chlorocyclopropyl quinazoline positional isomer. Its exact nitrogen sequence is preserved independently in the InChI connectivity layer.

An enquiry for this identity should carry CAS 898044-61-6, CID 42809123, and the complete 4-chloro-2-cyclopropyl name. When a structure file is attached, its cyclopropyl junction and both quinazoline nitrogens can be compared with the stated SMILES. The formula and InChIKey provide further checkpoints where a text label has been abbreviated. Keeping those exact identifiers together ensures that subsequent record discussion concerns this graph, without extending the page beyond verified identity data.
