  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  Picric  \Pi"cric\,  a.  [Gr.  ?  bitter.]  (Chem.) 
  Pertaining  to  or  designating,  a  strong  organic  acid  (called 
  picric  acid),  intensely  bitter. 
 
  Note:  Picric  acid  is  obtained  by  treating  phenol  with  strong 
  nitric  acid,  as  a  brilliant  yellow  crystalline 
  substance,  {C6H2(NO2)3.OH}.  It  is  used  in  dyeing  silk 
  and  wool,  and  also  in  the  manufacture  of  explosives,  as 
  it  is  very  unstable  when  heated.  Called  also 
  {trinitrophenol},  and  formerly  {carbazotic  acid}.
