Also known as: Diclofenac acid, Diclofenac free acid, 2-(2-((2,6-dichlorophenyl)amino)phenyl)acetic acid, 2-[2-(2,6-dichloroanilino)phenyl]acetic acid, Diclofenal, Dicrofenac, Diclophenac
Diclofenac is a monocarboxylic acid and phenylacetic acid derivative with the molecular formula C14H11Cl2NO2 and molecular weight approximately 296.14 g/mol. It is classified as a nonsteroidal anti-inflammatory drug and cyclooxygenase inhibitor. Diclofenac is used in multiple pharmaceutical formulations, including oral, topical dermal, and ophthalmic products; diclofenac salts such as diclofenac sodium and diclofenac potassium are distinct chemical forms of the same active moiety.

Reflects preclinical/research literature context only. Not a medical claim, dosing instruction, or treatment recommendation.
Evidence and administration details are formulation-specific and should not be transferred between diclofenac free acid, diclofenac sodium, diclofenac potassium, topical products, or ophthalmic products. Representative official labeling describes oral diclofenac sodium delayed-release tablets in 50 mg and 75 mg strengths, but these product strengths are not recorded as compound common sizes because they are formulation- and product-specific.

CAS RN 15307-86-5; PubChem CID 3033; ChEBI CHEBI:47381; FDA UNII 144O8QL0L1; molecular formula C14H11Cl2NO2; molecular weight 296.14 g/mol; IUPAC name 2-[2-(2,6-dichloroanilino)phenyl]acetic acid; InChIKey DCOPUUMXTXDBNB-UHFFFAOYSA-N; InChI InChI=1S/C14H11Cl2NO2/c15-10-5-3-6-11(16)14(10)17-12-7-2-1-4-9(12)8-13(18)19/h1-7,17H,8H2,(H,18,19); canonical SMILES C1=CC=C(C(=C1)CC(=O)O)NC2=C(C=CC=C2Cl)Cl
The parent compound is the free acid. Diclofenac sodium and diclofenac potassium are salts and should not be treated as identical material for physicochemical or formulation records. Diclofenac sodium delayed-release, extended-release, immediate-release diclofenac potassium, topical, and ophthalmic formulations may have different absorption and exposure characteristics.
