Sodium Hydrogen Phthalate Hemihydrate

1,2-Benzenedicarboxylic acid, monosodium salt has diverse applications across various fields:

• Buffering Agent: Used extensively in biochemical laboratories to maintain pH stability.
• Standard for Titration: Serves as a primary standard in acid-base titrations due to its stable and predictable dissociation behavior.
• Chemical Intermediate: Acts as an intermediate in the synthesis of various organic compounds including plasticizers and dyes.
• Pharmaceuticals: Utilized in formulations requiring pH control or stabilization .

Sodium hydrogen phthalate is primarily recognized for its role as a buffer in biological research. It helps maintain stable pH levels in solutions, which is crucial for many biochemical processes. Additionally, it acts as a primary standard for acid-base titrations due to its known dissociation constant . Its pharmacokinetics suggest that it is well-absorbed and distributed in biological systems when ingested or administered .
