Industrial Applications of Sodium 2-aminosulphanilate
| Industry | Application | Process |
|---|---|---|
| Dye Industry | Intermediate for reactive dyes | Serves as a diazo component and coupling component in the synthesis of reactive dyes (e.g., reactive red, reactive violet) via diazotization and coupling reactions. |
| Dye Industry | Intermediate for acid dyes | Used in the synthesis of acid dyes for dyeing wool, nylon, and other fibers. |
| Dye Industry | Intermediate for mordant dyes | Participates in the synthesis of mordant dyes, enabling specific shades on fibers via post-mordanting. |
| Pigment Industry | Intermediate for organic pigments | Used in the synthesis of azo organic pigments for coloring inks, paints, and plastics. |
| Chemical Reagents | Analytical reagent | Employed in chemical analysis as a test reagent or reference standard. |
Manufacturing Quality Control of Sodium 2-aminosulphanilate
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color and physical state (e.g., white or off-white crystalline powder) to determine compliance with standard descriptions. |
| Purity/Content Assay | High-Performance Liquid Chromatography (HPLC) | Separation is performed using a reversed-phase chromatographic column with an appropriate mobile phase (e.g., methanol-buffer system); quantification of the main component is achieved using a UV detector (e.g., at 254 nm). |
| Loss on Drying | Drying Method (Constant Weight at 105°C) | A specified amount of sample is dried at 105°C until constant weight is achieved; the percentage of mass loss is calculated to assess moisture and volatile content. |
| Residue on Ignition | High-Temperature Ashing | The sample is incinerated at high temperature (typically 600–800°C); the residual inorganic material is weighed to control the level of inorganic impurities. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, the content of hazardous heavy metal elements such as lead, arsenic, cadmium, and mercury is measured to ensure compliance with pharmacopoeial or industry limits. |
| pH Value | pH Meter Measurement | A solution of specified concentration (e.g., 1% or 5%) is prepared, and its acidity or alkalinity is measured using a calibrated pH meter to evaluate product stability and suitability. |
| Solubility | Solubility Test | Observe the dissolution behavior in specified solvents (e.g., water, ethanol) to confirm compliance with physicochemical characteristics such as "freely soluble in water". |
| Related Substances (Impurities) | HPLC with Gradient Elution | A high-sensitivity HPLC system with gradient elution is used to separate potential impurity peaks; total impurity levels and individual impurity limits are controlled by area normalization or external standard methods. |
| Melting Point | Capillary Melting Point Determination | The melting temperature range of the sample is measured as an auxiliary indicator for identification and purity assessment (note: some sulfonate salts may not exhibit a distinct melting point). |
| Ultraviolet Absorption Spectrum | UV-Visible Spectrophotometry | The absorption spectrum within a specific wavelength range (e.g., 230–300 nm) is measured for structural confirmation and preliminary purity screening. |
