1. Basic Info

Name: Carbamazepine
Alias: 5H-Dibenz[b,f]azepine-5-carboxamide
CAS No.: 298-46-4
Molecular Formula: C15H12N2O
Molecular Weight: 236.27

2. Physical & Chemical Properties

Physical Properties

  1. Appearance: White or off-white crystalline powder, odorless
  2. Solubility: Insoluble in water; slightly soluble in ethanol, acetone; soluble in chloroform, DMSO, dichloromethane
  3. Melting Point: 189–193 ℃
  4. UV feature: Characteristic absorption peaks in methanol ultraviolet band
  5. Hygroscopy: Non-hygroscopic under normal humidity
  6. Crystal form: Flaky crystal recrystallized from ethanol

Chemical Properties

  1. Molecular structure: Dibenzazepine fused ring with carboxamide functional group, tricyclic anticonvulsant structure
  2. Hydrolysis characteristic: Amide group hydrolyzes under strong acid/alkali heating to generate dibenzazepine and ammonia
  3. Photodegradation: Sensitive to ultraviolet light; long-term illumination produces colored oxidation impurities
  4. Oxidation: Easily oxidized by strong oxidants to form nitrogen oxide derivatives
  5. Thermal stability: Stable below 160 ℃; above melting point slight thermal decomposition
  6. Acid-base property: Neutral compound, does not form salts with dilute acid/alkali
  7. Compatibility: Compatible with halogenated solvents; avoid mixing with strong oxidants, concentrated acid

3. Main Application Fields

  1. Antiepileptic drug, treat partial seizures, generalized tonic-clonic seizures
  2. Clinical medicine for trigeminal neuralgia, bipolar mania depression, diabetes insipidus

2. Forensic Toxicology Reference Standard

HPLC/LC-MS standard substance for drug screening and blood drug concentration detection

3. Pharmacological Research Reagent

Cell and animal experiment reagent for studying sodium ion channel regulation mechanism

4. Pharmaceutical Synthetic Intermediate

Raw material for carbamazepine sustained-release preparations, derivative analog synthesis
