Purified water usp - obtained by distillation or ion exchange treatment. ph between 5 & 7; total organic content (toc) standard < 500ppb. Water for injection usp - same standards as purified water but is also free of pyrogens; can be used in the preparation of parenteral (injectable) solutions. Sterile water for injection usp - water for injection that has been sterilized and packaged in single dose containers (1l or less) of type i or ii glass.
