Description

Bathophenanthroline is a high-purity, heterocyclic organic compound widely recognized as a highly sensitive and selective chelating agent for ferrous ions (Fe²⁺). Its primary value lies in its ability to form a stable, intensely colored red complex with Fe²⁺, making it indispensable for quantitative colorimetric analysis. This product is essential for researchers and quality control laboratories in the pharmaceutical, environmental, and industrial sectors requiring precise iron quantification and trace metal analysis. Bathophenanthroline CAS NO 1662-01-7 is a critical reagent for ensuring product purity and compliance in various analytical protocols.

Application

• Spectrophotometric Iron Determination: Primary reagent for the colorimetric assay of ferrous iron in water, pharmaceuticals, food, and biological samples.
• Pharmaceutical QC: Used in purity testing of active pharmaceutical ingredients (APIs) and excipients to detect trace iron impurities.
• Environmental Analysis: Employed in testing wastewater, soil extracts, and industrial effluents for iron contamination.
• Biochemical Research: Serves as a specific chelator in studies of iron metabolism, enzyme function, and oxidative stress.
• Industrial Process Control: Monitors iron levels in chemical manufacturing processes, catalysts, and high-purity materials.
• Reagent Grade Chemical: A key component in prepared test kits and standardized solutions for laboratory use.
