  "abstract": "We conducted a photometric and kinematic analysis of the young open cluster NGC 2345 using CCD \\emph{UBV} data from 2-m Himalayan Chandra Telescope (HCT), \\emph{Gaia} Data Release 3 (DR3), 2MASS, and the APASS datasets. We found 1732 most probable cluster members with membership probability higher than 70$\\%$. The fundamental and structural parameters of the cluster are determined based on the cluster members. The mean proper motion of the cluster is estimated to be $\\mu_{\\alpha}cos\\delta$ = ${-1.34}\\pm0.20$ and $\\mu_{\\delta}$= $1.35\\pm 0.21$ mas $yr^{-1}$. Based on the radial density profile, the estimated radius is $\\sim$ 12.8 arcmin (10.37 pc). Using color-color and color-magnitude diagrams, we estimate the reddening, age, and distance to be $0.63\\pm0.04$ mag, 63 $\\pm$ 8 Myr, and 2.78 $\\pm$ 0.78 kpc, respectively. The mass function slope for main-sequence stars is determined as $1.2\\pm 0.1$. The mass function slope in the core, halo, and overall region indicates a possible hint of mass segregation. The cluster's dynamical relaxation time is 177.6 Myr, meaning ongoing mass segregation, with complete equilibrium expected in 100-110 Myr. Apex coordinates are determined as $-40^{\\circ}.89 \\pm 0.12, -44^{\\circ}.99 \\pm 0.15$. The cluster's orbit in the Galaxy suggests early dissociation in field stars due to its close proximity to the Galactic disk.",
