The title compound, C{sub 13}H{sub 14}O{sub 2}N{sub 3}Cl, has been synthesized by the reaction of chloroacetyl chloride with 4-aminoantipyrine in basic media and characterized by FT-IR, CHN elemental analysis, UV-Vis, TGA, DTA, DSC and single crystal X-ray diffraction. crystals are monoclinic, sp. gr. P2{sub 1}/c, a = 6.9994(6), b = 12.4035(13), c = 15.836(2) Å, β = 100.367(9)°, Z = 4. The crystal structure is stabilized by N–H···O and C–H···O interactions, the former interactions result in the formation of dimers corresponding to R{sub 2}{sup 2} (10) graphset motif and the dimers are further connected by C–H···O hydrogen bonding forming chains. In addition, the thermal stability of the compound was determined by TGA, DTA, DSC analysis, and absorption at λ{sub max} = 298 nm was determined by UV-Vis spectrophotometer.
