PIPES Sodium Salt 99.0% High Purity Grade

Synonym(s): OmniPur® PIPES, Sodium Salt

Description

Our high-purity PIPES Sodium Salt (Sesquisodium Salt) is supplied as white crystalline powder, with a molecular weight of 335.3 g/mol and CAS no. 100037-69-2. This biochemical-grade reagent is manufactured to meet stringent quality requirements: purity ≥ 99.0% (or ≥ 96.5%, depending on batch), heavy metals ≤ 5 ppm, moisture ≤ 4.0%. In aqueous solution (1.0% at 25 °C), the pH falls between 6.5–7.1. Additionally, the low UV absorbance at 260 nm and 280 nm (≤ 0.05) ensures minimal interference with nucleic acid and protein assays.

PIPES (piperazine-N,N′-bis(2-ethanesulfonic acid)) is widely regarded for its excellent buffering capacity near physiological pH, making it a preferred choice for biological and biochemical experiments requiring stable pH and high purity.

Specifications

Features

• High purity: ≥ 99.0% grade ensures minimal impurities for sensitive biological applications.

• Low heavy metal content: ≤ 5 ppm — reduces risk of metal-induced toxicity or interference in cell culture or enzyme reactions.

• Low moisture & stable quality: moisture ≤ 4.0% ensures consistent batch performance and long shelf life.

• Low UV absorbance: ≤ 0.05 at 260 nm and 280 nm — minimizes background absorption, ideal for nucleic acid, protein or other spectrophotometric assays.

• Optimal buffering capacity at physiological pH: pH 6.5–7.1 in 1.0% aqueous solution — stable buffering near neutral pH range.

• Clear, colorless solution when dissolved: ensures visual clarity and ease of use in buffer preparations.

Applications

• Preparation of buffers for cell culture, especially when precise pH control is required.

• Use in molecular biology protocols, such as DNA/RNA purification, enzyme reactions, electrophoresis, where low UV background is critical.

• Formulation of biochemical assay buffers — enzymatic assays, protein work, immunoassays, where purity and minimal metal contamination matter.

• Physiological-pH buffer systems for in-vitro biological research.

• Any application demanding high-quality, low-contaminant buffering reagents.
