The entry for 4-(4-Fluorophenyl)phthalazin-1(2H)-one is anchored to CAS Registry Number 1766-63-8 and molecular formula C14H9FN2O. The same CAS maps to PubChem CID 722258. PubChem lists 4-(4-Fluorophenyl)-1,2-dihydrophthalazin-1-one as its record title, giving a second reference point for the name shown on this page. Reading the name, CAS number, and formula together helps keep this individual record distinct from near matches.
Structure matching is supported by SMILES C1=CC=C2C(=C1)C(=NNC2=O)C3=CC=C(C=C3)F and InChIKey ZMXMVYKPVMNLOJ-UHFFFAOYSA-N. PubChem supplies the IUPAC name 4-(4-fluorophenyl)-2H-phthalazin-1-one. Alongside the CAS number and formula, these fields agree with the unique CID in the official record. They provide a more precise comparison basis than a title alone when spelling, punctuation, or naming order differs.
An enquiry may include the CAS number, a preferred name, the formula, or a structure representation when those details are known. State the feature that separates the requested compound from a related entry. The purpose of this page is to make the verified identity set visible; questions that extend beyond those fields should proceed through the relevant enquiry channel. For the phthalazinone entry, retain the para-fluorophenyl description when supplying a drawing. The carbonyl-containing phthalazine framework is reflected in the stated SMILES. CID 722258 provides the common external reference for that graph. This comparison route avoids treating punctuation variants as different compounds.
