The objective of the present work is to investigate the chemically reacting micropolar nanofluid flow past an inclined permeable stretching sheet. The flow is exposed in the magnetic and thermally radiative environment and convective boundary conditions are taken into consideration to form the complete description of the flow model. The appropriate similarity invariants are used to obtain the system of the non-linear ordinary differential equation. The well-known Runge-Kutta fourth-order method is worked out with a shooting technique for numerical investigation. The behavior of fluid motion, temperature, concentration, and engineering quantities for arising physical parameters is sketched through graphs and discussed in detail. The tabular comparison is used to provide the validation of current work. Outputs demonstrate flow decrement, which is due to the produced Lorentz force that itself is the result of the enhancement in magnetic parameter and inclination of angle, and rise in the profiles of porosity index. The fluid temperature exceeds in conjunction with the accumulation of radiative heat, dissipation heat, as well as thermophoresis and Brownian motion. Physical engineering supporting forces like Skin friction and heat transfer rates are favorable for magnetic and material parameters but the mass transfer rate exhibits an opposite response.
