3,5-DiBr-PAESA sodium
Based on 1 Customer Validation
3,5-DiBr-PAESA sodium is a water-soluble pyridylazo-based highly sensitive chromogenic reagent. With the assistance of EDTA for masking copper and bromide ions for dissociating silver chelates, 3,5-DiBr-PAESA sodium enables accurate determination of sub-milligram level silver ions in strongly acidic high-copper systems via flow injection spectrophotometry.

Solvent & Solubility
DMSO : 50 mg/mL (94.66 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : 10 mg/mL (18.93 mM; ultrasonic and warming and heat to 60°C)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (protect from light). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.
