One of the most important questions in blazar physics is the origin ofbroadband emission and fast-flux variation. In this work, we studied thebroadband temporal and spectral properties of a TeV blazar 1ES 1727+502 andexplore the one-zone synchrotron-self Compton (SSC) model to fit the broadbandspectral energy distribution (SED). We collected the long-term (2014-2021)multiband data which includes both the low and high flux states of the source.The entire light curve is divided into three segments of different flux statesand the best-fit parameters obtained by broadband SED modeling corresponding tothree flux states were then compared. The TeV blazar 1ES 1727+502 has beenobserved to show the brightest flaring episode in X-ray followed by optical-UVand gamma-ray. The fractional variability estimated during various segmentsbehaves differently in multiple wavebands, suggesting a complex nature ofemission in this source. This source has shown a range of variability time fromdays scale to month scale during this long period of observations between2014-2021. A "harder-when-brighter" trend is not prominent in X-ray but seen inoptical-UV and an opposite trend is observed in gamma-ray. The complex natureof correlation among various bands is observed. The SED modeling suggests thatthe one-zone SSC emission model can reproduce the broadband spectrum in theenergy range from optical-UV to very high energy gamma-ray.
