Regulatory agencies’ push for the substitution of n-propyl bromide (1-bromopropane or nPB) with more environmentally responsible alternatives has gotten more clarity. This transition can be a daunting task for those using nPB as a critical part of their solvent cleaning operations, however there are viable alternatives available.
