I suspect the problem is not what you think it is because your code works fine with your data, for me anyway:

Code:
while(<DATA>){
   if (/userName\s+:\[(..*)\]/){
      $User_Name = $1;
      print "User_Name before concatenation is = $User_Name\n";
      $User_Name =~ s/\s+//g;
      $User_Name= "'"  .   $User_Name     .  "'";
      print "User_Name = $User_Name\n";
   }
}

__DATA__
pid 2172 tid 3124: 160: 10110847: userName :[app@abc.com]
pid 2172 tid 3124: 160: 10110847: userName :[napp@abc.com]
pid 2172 tid 3124: 160: 10110847: userName :[12345]
pid 2172 tid 3124: 160: 10110847: userName :[app@abc_sde.com]
pid 2172 tid 3124: 160: 10110847: userName :[567890]
pid 2172 tid 3124: 160: 10110847: userName :[dfgehj]

and the output is:

Code:
User_Name before concatenation is = app@abc.com
User_Name = 'app@abc.com'
User_Name before concatenation is = napp@abc.com
User_Name = 'napp@abc.com'
User_Name before concatenation is = 12345
User_Name = '12345'
User_Name before concatenation is = app@abc_sde.com
User_Name = 'app@abc_sde.com'
User_Name before concatenation is = 567890
User_Name = '567890'
User_Name before concatenation is = dfgehj
User_Name = 'dfgehj'

lldptool(8)							       Linux							       lldptool(8)

NAME

       APP - Show / manipulate APP TLV configuration

SYNOPSIS

       lldptool -t -i ethx -V APP [-c app]

       lldptool -T -i ethx -V APP [-d] app=prio,sel,pid

DESCRIPTION

       The  APP  TLV  is an informational TLV and will advertise the current configured application table. If the peer APP TLV and a local APP TLV
       match the same selector and protocol field the local parameter is used.

ARGUMENTS

       app    Configures a local application data field using the three parameters: priority (prio), selector (sel), and protocol  (pid).  The	-d
	      option can be provided to remove an entry which matches the three parameters.

Theory of Operations
       The  APP  TLV is an informational TLV for most end stations. It is not expected that setting APP data should be required. Peer data will be
       processed and added to the application data table by default assuming there does not already exist a local entry with matching selector and
       priority fields.

       By adding APP data to the application table it is available for applications, eg iscsid, to query. Applications query for a specific proto-
       col and selector and may use this data to map traffic to the corresponding traffic class.

EXAMPLE &; USAGE
       Configure ISCSI application for priority 4 on eth2
	      lldptool -T -i eth2 -V APP app=4,2,3260

       Configure FCoE application for priority 3 on eth2
	      lldptool -T -i eth2 -V APP app=3,1,35078

       Remove FCoE application for priority 3 on eth2
	      lldptool -T -i eth2 -V APP -d app=3,1,35078

       Display locally configured application table on eth2
	      lldptool -t -i eth2 -V APP -c app

       Display last transmitted APP TLV on eth2
	      lldptool -t -i eth2 -V APP
