PIPES-Na 99% Biochemical Grade

Synonym(s): 1,4-Piperazinediethanesulfonic acid sodium salt, Piperazine-N,N′-bis(2-ethanesulfonic acid) sodium salt

Description

PIPES-Na (Piperazine-N,N′-bis(2-ethanesulfonic acid) sodium salt) is a high-quality biochemical-grade buffer reagent supplied as a white powder. With a molecular weight of 324.3 and ≥ 99% purity, our PIPES-Na is designed to meet rigorous research standards. Upon dissolution in water (1% w/v), it forms a clear, colorless solution with minimal absorbance at 260 nm and 280 nm — reflecting its high purity and minimal contaminating nucleic acids or proteins. The buffer exhibits a working pH of 4.0–5.0 (1% solution at 25 °C), making it a reliable pH buffer for biochemical and cell biology applications.

Specifications

Features

• High purity (≥ 99%) — ensures minimal background impurities for sensitive experiments.

• Biochemical grade quality — suitable for molecular biology, cell culture, and protein/RNA work.

• Clear, colorless solution — dissolves readily to produce a transparent 1% aqueous solution, facilitating accurate downstream analysis.

• Low nucleic acid and protein absorbance — A260 ≤ 0.050, A280 ≤ 0.040 for 1% solution, avoiding interference in spectrophotometric assays.

• Consistent pH stability — pH 4.0–5.0 (1% solution at 25 °C), providing a stable acidic buffer environment.

• Low moisture content — ≤ 3.0% moisture helps maintain stability and long shelf-life.

Applications

• Molecular biology & nucleic acid research — ideal for RNA/DNA extraction, purification, and enzymatic reactions requiring low background absorbance.

• Protein biochemistry — useful in protein purification, enzyme assays, or chromatography workflows where pH stability and buffer purity are critical.

• Cell culture & tissue work — suitable for preparing buffer solutions in various cell biology experiments, particularly when an acidic buffer environment is required.

• Buffer preparation for sensitive assays — recommended for downstream applications such as spectrophotometry, fluorometry, or any assay needing minimal background interference.
