Industrial Applications of BROMOCRESOL GREEN SODIUM SALT
| Industry | Application | Process |
|---|---|---|
| Chemical Analysis | pH Indicator | Used in acid-base titrations; color change range: pH 3.8 (yellow) to 5.4 (blue); commonly employed for laboratory determination of solution acidity or alkalinity |
| Biochemistry | Protein-Binding Indicator | Applied in protein quantification assays, leveraging its color shift upon binding to proteins for detection |
| Pharmaceutical R&D | Buffer Component | Incorporated into pH-buffering systems for cell culture or biochemical reactions to monitor acid-base stability |
| Environmental Monitoring | Water Quality Analysis | Used for pH measurement of surface water and wastewater samples to assess acidic or alkaline contamination |
| Educational Laboratories | Demonstration Reagent | Employed in chemistry instruction for acid-base indicator experiments, visually demonstrating color transitions induced by pH changes |
Manufacturing Quality Control of BROMOCRESOL GREEN SODIUM SALT
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantifies bromocresol green concentration based on absorbance at characteristic λ_max (~617 nm in basic medium) using Beer-Lambert law. |
| Loss on Drying (LOD) | Gravimetric Analysis (Thermogravimetry) | Measures mass loss after drying at 105 °C to determine volatile content including residual solvents and moisture. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash) | Determines inorganic impurities by incinerating sample at 600–700 °C and weighing residual sulfate ash. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) or ICP-OES | Quantifies total heavy metals by atomization and measurement of elemental absorption/emission; reported as lead equivalent. |
| Chloride Impurity | Potentiometric Titration with AgNO₃ | Measures chloride ions via argentometric titration using silver nitrate and a silver indicator electrode. |
| Related Substances (Impurity Profile) | High-Performance Liquid Chromatography (HPLC) | Separates and quantifies structurally related impurities (e.g., bromination by-products, hydrolysis products) using reversed-phase C18 column and UV detection. |
| pH of 0.04% Aqueous Solution | pH Potentiometry | Measures hydrogen ion activity in standardized aqueous suspension/solution using calibrated pH electrode. |
| Melting Point | Capillary Melting Point Determination | Determines temperature range at which solid transitions to liquid, indicating purity and identity via thermal behavior. |
| Solubility in Ethanol (95%) | Visual Qualitative Test | Assesses complete dissolution in specified solvent under controlled conditions to verify expected solubility behavior. |
| Specific Optical Rotation | [α]D Measurement (Polarimetry) | Measures rotation of plane-polarized light to confirm chiral integrity and absence of racemization (if applicable; typically low but specified). |
