Abstract	We propose a sensitive INTEGRAL ToO observation as part of a multifrequency campaign on the prominent \gray\ blazar 3C279 during a flux high-state in the optical bandin order to measure 1) its high-state multifrequency spectrum, 2) its X- and hard X-ray spectrum up to a about 200 keV, and3) its variability behaviour at hard X-rays.The proposed INTEGRAL observation will increase our knowledge on the largely unknownhard X-ray properties of 3C 279. The comparison of the newly measuredhigh-state to the already observed low-state multifrequency spectrumwill reveal new insights in its overall emission scenario.Because the observed radiation of 3C 279 is almost purely of non-thermal origin, we are studying jet physics and subsequently the physics of particle acceleration by the proposed observation.

Mission Description	The INTEGRAL (International Gamma-Ray Astrophysics Laboratory) mission, launched by the European Space Agency (ESA) on October 17, 2002, was designed to study high-energy phenomena in the universe. INTEGRAL was operating until february 2025 and it was equipped with three high-energy instruments: the Imager on Board the INTEGRAL Satellite (IBIS), the Spectrometer on INTEGRAL (SPI), and the JEM-X (Joint European Monitor for X-rays). Its Optical Monitoring Camera (OMC) provided optical V-band magnitude measurements, complementing the high-energy observations.
