The phrase "active in the range of" is correct and usable in written English.
It can be used to describe involvement or participation within a specific area or field of activity.
Example: "The researchers are active in the range of renewable energy technologies, focusing on solar and wind power."
Alternatives: "engaged in the field of" or "involved in the area of".
The heat-activated cation channel TRPA1 shows some activity at 25°C, and is fully active in the range of 27°C 32°C (Hamada et al., 2008).

The crude enzyme showed activity at an optimal temperature of 55 °C and it remained highly active in the range of 50 65 °C.
Immobilized S. cerevisiae were active in the range of initial pH values of 4.5 6.4, and achieved the maximum ethanol productivity at a pH of 5.5.
All catalysts were active in the range of 200 350 °C and thus are candidates to be used in a single stage of WGSR at intermediate temperatures.
The investigation of the effect of temperature on the immobilized enzyme indicated that the enzyme was active in the range of 25 60 °C and the optimal temperature of rBGLa was shifted to 50 °C when immobilized.
Surface active sites in the range of tens of microns from the powder/Nafion® interface can be involved in interfacial reactions.
This impulse response exhibits an "active" region in the range of only 8 12 milliseconds duration, and, consequently, it is dominated by "inactive" regions, where magnitudes are close to zero making the impulse response sparse.
A Finnish study that combined cycling and walking to work versus nonactive commuting also showed significantly lower relative risks for active commuters in the range of 0.71 and 0.79 (Hu et al. 2004).
Similar results are obtained when soot oxidation is carried out under temperature programmed oxidation (TPO) conditions where the maximum oxidation temperatures are located between 250 and 270 °C with the onset of oxidation for the most active samples in the range of 50 100 °C.
Regarding COX-2, compounds 5b, 4a and 3b were the most active with IC50 in the range of 0.55 0.87 μM.
