Industrial Applications of 631-22-1
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Synthesis of antiviral agents (e.g., acyclovir analogues) and side chains of β-lactam antibiotics | Used as a bromoalkylating reagent in substitution reactions with compounds containing active hydrogens (e.g., amines, thiols), or employed in decarboxylation/elimination sequences to construct alkenyl or alkynyl frameworks |
| Agrochemical Intermediates | Preparation of brominated heterocyclic insecticides and plant growth regulators | Participates in cyclization reactions (e.g., condensation with hydrazines or amidines) to generate brominated heterocyclic pharmacophores such as pyrimidines and triazoles |
| Organic Synthesis | Introduction of bromomethyl or dibromomethylene functional groups for C–C bond formation | Undergoes Knoevenagel condensation with aldehydes/ketones under basic conditions, or acts as a bifunctional electrophile in reactions with bifunctional nucleophiles (e.g., dithiols, diamines) to synthesize heterocyclic compounds |
| Materials Science | Synthesis of brominated flame retardant precursors and functionalized polymer monomers | Converted via transesterification or hydrolysis to dibromomalonate, followed by condensation polymerization with polyols/polyamines; alternatively, used in radical bromination to modulate polymer flame retardancy |
Manufacturing Quality Control of 631-22-1
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a calibrated column and detector. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent, measuring endpoint coulometrically or volumetrically. |
| Acidity (as HBr) | Acid-Base Titration with NaOH | Neutralization of acidic impurities (e.g., residual HBr) using standardized sodium hydroxide solution and potentiometric or visual endpoint detection. |
| Residual Solvents (Ethanol, DCM) | Gas Chromatography (GC) with FID or TCD | Separation and quantification of volatile solvents by retention time and response factor relative to internal/external standards. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element detection via ionization in plasma and mass-selective quantification at isotopic masses, achieving sub-ppt sensitivity. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Anion separation on an ion-exchange column followed by quantitative detection based on electrical conductivity of eluted chloride ions. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Comparison of sample color intensity in solution against APHA platinum-cobalt standard solutions at 430 nm absorbance. |
| Density | Digital Density Meter (Oscillating U-tube) | Measurement of sample density via resonant frequency shift of a vibrating U-shaped tube filled with the liquid. |
| Refractive Index | Digital Refractometer | Determination of refractive index by measuring the critical angle of total internal reflection at the prism-sample interface. |
| Non-Volatile Residue | Gravimetric Analysis (Weight Loss on Drying) | Evaporation of volatile components under controlled temperature/vacuum, followed by weighing of residual solids. |
| Appearance (Clarity) | Visual Inspection in Nessler Cylinder | Assessment of liquid clarity and presence of suspended particles or haze against a black/white background under controlled lighting. |
| Distillation Range | Micro Distillation Apparatus (ASTM D1078) | Determination of initial boiling point, final boiling point, and % distilled at specified temperatures using standardized distillation equipment. |
