In this work, we focus on formaldehyde deuteration in the protobinary system NGC\\,1333 IRAS\\,4A, located in the Perseus molecular cloud. Using high-resolution ($\\sim$\\,100\\,au) ALMA observations, we investigate the [D$_2$CO]/[HDCO] ratio along the cavity walls of the outflows emanating from IRAS\\,4A1.
