Basic Information

Product Name: Phenoxazine, also known as 10H-Phenoxazine, PXZ;

CAS Number: 135-67-1 (EINECS: 205-210-8)

Molecular Formula: C??H?NO

Molecular Weight: 183.21 g/mol

Structural Formula: C??H?NO (heterocyclic aromatic structure, two benzene rings linked by one nitrogen and one oxygen atom)

Classification: Organic heterocyclic compound, chemical intermediate, dye & pigment raw material, photosensitive material agent, biochemical reagent

Physical & Chemical Properties

Phenoxazine is a pale yellow to greenish-gray needle-like crystalline powder, odorless, with a conjugated aromatic structure formed by two benzene rings linked via one nitrogen and one oxygen atom. It is almost insoluble in water, soluble in ethanol, ether, benzene, methanol, DMF and other polar organic solvents, and soluble in mineral acids (forming yellow to red solutions). It has good chemical stability at room temperature, is sensitive to air and light, and may oxidize and darken when exposed to air for a long time.

Key physical and chemical parameters are detailed in the specification table below, meeting the requirements of high-purity and industrial grades.

Main Uses

Phenoxazine is a critical heterocyclic chemical with wide applications in multiple industries:

Dye & Pigment Industry: Key intermediate for synthesizing acridine dyes, azo dyes and fluorescent dyes, widely used in textile printing and dyeing, ink and coating industries.
Photosensitive Materials: Used as a photosensitive agent and photoinitiator in photocopying plates, printed circuit boards and laser printing materials, with excellent photosensitive activity.
Chemical Synthesis: Precursor for synthesizing phenoxazine derivatives, nitrogen-containing heterocyclic compounds and pharmaceutical intermediates, participating in various organic synthesis reactions.
Other Uses: Applied as a preservative in wood, textiles and adhesives; also used in biochemical research, battery materials and electronic component manufacturing.

Packaging & Storage

Packaging Method

Lab Grade: 1g, 5g, 10g, 25g sealed glass bottles or aluminum foil bags; 100g, 500g, 1kg, 5kg HDPE plastic bottles, suitable for laboratory use and small-batch sampling.

Industrial Grade: 25kg/bag (inner PE bag, outer three-layer kraft paper bag), 50kg/200kg iron drum with inner polyethylene liner; customized packaging available per customer requirements.

Storage Method

Store in a cool, dry, dark and well-ventilated warehouse at a temperature of 2-8°C (refrigerated storage recommended). Keep containers tightly sealed under inert gas protection (nitrogen filling recommended) to prevent moisture absorption, oxidation and light-induced decomposition. Avoid contact with air, strong oxidants, strong acids and strong bases; keep away from fire, heat sources and direct sunlight. Shelf life is 24 months under standard sealed and inert atmosphere storage conditions.
