Manufacturing Quality Control of 1,3-Diethylurea
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies 1,3-diethylurea by reaction with standardized HCl in aqueous medium using methyl orange indicator. |
| Water Content | Karl Fischer Titration | Measures trace water via iodine-sulfur dioxide redox reaction in methanol-based reagent. |
| Appearance | Visual Inspection | Assesses physical state and clarity against standard colorless, transparent liquid reference under controlled lighting. |
| Color (APHA) | Spectrophotometric Comparison | Compares sample absorbance at 430 nm to APHA platinum-cobalt standard solutions. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by ashing at 700-800 C and weighing residue. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies Pb, Cd, Hg, As, and other heavy metals after acid digestion and atomization. |
| Chloride Content | Potentiometric Titration | Measures chloride ions using silver nitrate titrant and silver/silver chloride electrode detection. |
| Residual Solvents | Gas Chromatography (GC-FID) | Separates and quantifies volatile organic solvents (e.g., ethanol, acetone) using flame ionization detection. |
| Melting Point | Capillary Melting Point Determination | Determines solidification temperature range using calibrated capillary apparatus per USP <741>. |
| Specific Gravity | Digital Density Meter | Measures mass per unit volume at 20 C relative to water using oscillating U-tube principle. |
| pH of Aqueous Solution | pH Meter Measurement | Determines hydrogen ion activity in 10% w/w aqueous solution using calibrated glass electrode. |
| Organic Impurities (Related Substances) | High-Performance Liquid Chromatography (HPLC-UV) | Separates and quantifies structurally related compounds (e.g., diethylamine, ethyl carbamate) using UV detection at 210 nm. |
