This study presents the first measurement of the f&sub(1)(1285) resonance using the ALICE detector in inelastic proton-proton collisions at a center-of-mass energy of 13 TeV. The resonance is reconstructed at midrapidity (|𝑦| < 0.5) through the hadronic decay channel f&sub(1)(1285) *> K&sup(0)&sub(S)K&sup(*()*p*). Key measurements include the determination of its mass, transverse-momentum integrated yield, and average transverse momentum. Additionally, the ratio of the transverse-momentum integrated yield of f&sub(1)(1285) to pion is compared with calculations from the canonical statistical hadronization model. The model calculation, assuming a zero total strangeness content for f&sub(1)(1285), reproduces the data within 1*s deviation, shedding light on the quark composition of f&sub(1)(1285).
