Overview
PPMP (Phenylphosphonic acid mono-p-nitrophenyl ester) is a specialized chemical compound primarily utilized in organic synthesis and as a flame retardant. Its molecular structure combines a phenyl group with a phosphonic acid ester, making it effective in various industrial applications. The compound is known for its stability and reactivity, which are essential in synthetic chemistry. PPMP is commonly sourced by B2B buyers in the chemical industry for its role as an intermediate in the production of more complex molecules. Its applications span across multiple sectors, including pharmaceuticals, agrochemicals, and materials science. The compound's flame-retardant properties also make it valuable in manufacturing safer materials.
Physical and Chemical Properties
PPMP appears as a white to off-white crystalline powder with a molecular weight of 279.18 g/mol. It has a melting point range of approximately 120-125°C, which is typical for organic phosphonic acid esters. The compound is soluble in common organic solvents like acetone and ethanol but has limited solubility in water. Key chemical properties of PPMP include its reactivity as an ester and its ability to act as a flame retardant. The presence of both phosphonic and nitro groups in its structure contributes to its thermal stability and effectiveness in reducing flammability in materials. These properties are critical for its use in high-performance applications.
Main Applications
PPMP is predominantly used as a flame retardant in polymers and textiles, where it helps reduce the flammability of materials without significantly altering their physical properties. Its effectiveness stems from its ability to release phosphoric acid upon heating, which forms a protective char layer. In addition to its flame-retardant applications, PPMP serves as an intermediate in organic synthesis. It is involved in the production of various phosphonate derivatives, which are used in pharmaceuticals, agrochemicals, and specialty chemicals. The compound's versatility makes it a valuable asset in industrial chemistry.
Safety and Storage
Handling PPMP requires adherence to strict safety protocols due to its potential health hazards. Direct contact with skin or eyes can cause irritation, and inhalation of dust should be avoided. Proper personal protective equipment (PPE), including gloves and goggles, is recommended. Storage conditions for PPMP include keeping the compound in a cool, dry place away from moisture and direct sunlight. Containers should be tightly sealed to prevent contamination and degradation. Proper labeling and compliance with local safety regulations are essential for safe storage and handling.
B2B Procurement Guide
When procuring PPMP, B2B buyers should prioritize suppliers who provide detailed specifications, including purity levels and CAS number verification. It is advisable to request material safety data sheets (MSDS) to ensure compliance with safety standards. Price ranges for PPMP typically vary between $50 and $100 per kilogram, depending on quantity and purity. Buyers should also consider logistical factors such as packaging, transportation, and storage requirements to maintain product integrity. Establishing long-term relationships with reliable suppliers can ensure consistent quality and availability.
