CAS No.: 5144-89-8

EINECS No.: 225-908-4

Molecular Formula: C??H?N?·H?O

Molecular Weight: 198.22 g/mol

Classification: Organic heterocyclic compound, phenanthroline derivative, analytical reagent, chelating agent, pharmaceutical intermediate, research reagent, fine chemical, metal ion indicator

Physical & Chemical Properties

Appearance: White to off-white crystalline powder, odorless; stable under normal conditions, incompatible with strong oxidizing agents and strong acids; light-sensitive; slightly hygroscopic; may cause mild irritation upon contact with skin and eyes.

Density: 1.26 g/cm3 (25℃, predicted); refractive index n??/D 1.665 (predicted); LogP: 1.92 (predicted); PSA: 25.78; precise mass: 198.0847; UV absorption λmax: 222, 262, 345 nm.

Melting Point: 100-104℃ (lit.); loses crystal water at 100℃, anhydrous form melts at 117-119℃.

Boiling Point: 365.1±15.0℃ (predicted, atmospheric pressure); sublimes at high temperature; no obvious decomposition before boiling.

Solubility: Slightly soluble in water (1.1 g/100mL at 25℃); soluble in ethanol, methanol, acetone, chloroform and benzene; freely soluble in dilute acids and DMSO; solubility increases in hot water.

Flash Point: 165.8±19.8℃ (predicted); Vapor Pressure: 0.0±0.8 mmHg (25℃, predicted); pKa: 4.9 (25℃, for conjugate acid).

Purity: ≥98.0% (analytical grade, HPLC); ≥99.0% (high-purity grade); ≥99.5% (for analytical use, AR grade).

Storage Condition: Sealed, stored in a cool and dry place at room temperature, protected from light and moisture; keep container tightly closed; avoid high temperature, open flame and contact with oxidizing agents and strong acids; store in a well-ventilated warehouse; separate from incompatible substances; protect from light to prevent discoloration.

Main Uses

Analytical Chemistry Field: Widely used as a metal ion indicator (ferroin indicator) for the titration of iron(II) ions; acts as a chelating agent for transition metal ions (Fe2?, Cu2?, Zn2?, etc.); used in the spectrophotometric determination of trace metals.
Pharmaceutical & Intermediate Field: As a pharmaceutical intermediate for the synthesis of phenanthroline derivatives with antibacterial, antiviral and anticancer activities; used in the research and development of metal-based drugs.
Research & Laboratory Field: Used as a research reagent in molecular biology, coordination chemistry and analytical chemistry; used to study metal ion complexation reactions, DNA intercalation and enzyme inhibition; used as a reference substance for chemical analysis.
Other Fields: Used in the production of dyes and pigments; applied in electroplating as a complexing agent; used in water treatment for the removal of heavy metal ions; used as a catalyst in organic synthesis reactions.
