2-Phenylacetophenone oxime

Updated: 2026-07-22

Overview

2-Acetophenone oxime (CAS: 613-90-1) is an organic compound derived from acetophenone. It serves as a versatile intermediate in chemical synthesis, particularly in pharmaceuticals and agrochemicals. Its oxime functional group makes it valuable for chelation and coordination chemistry. This compound is typically supplied as a white crystalline powder, ensuring ease of handling and storage. Industrial applications often leverage its reactivity in producing more complex molecules, such as active pharmaceutical ingredients (APIs) and crop protection agents.

Physical and Chemical Properties

2-Acetophenone oxime exhibits a molecular weight of 135.16 g/mol and a melting point of 80-82°C. It is soluble in common organic solvents like ethanol, methanol, and ether, but has limited solubility in water. The crystalline form ensures stability under standard storage conditions. The oxime group (-NOH) in its structure enables it to act as a ligand in metal coordination complexes. This property is exploited in catalysis and analytical chemistry. Its stability under normal conditions makes it suitable for long-term storage when kept away from moisture and strong oxidizers.

Main Applications

The primary use of 2-acetophenone oxime is as an intermediate in pharmaceutical synthesis, where it contributes to the production of analgesics and anti-inflammatory drugs. It also finds applications in agrochemical formulations, particularly in the synthesis of herbicides and insecticides. Additionally, its chelating properties are utilized in specialty chemicals, such as corrosion inhibitors and metal deactivators. Research labs may employ it as a reagent for organic transformations, including Beckmann rearrangements.

Safety and Storage

While 2-acetophenone oxime is not classified as highly hazardous, proper safety measures are essential. Avoid inhalation of dust and direct contact with skin or eyes. Use gloves, goggles, and a lab coat when handling. In case of exposure, rinse thoroughly with water. Storage should be in a tightly sealed container, placed in a cool, dry, and well-ventilated area. Keep away from oxidizing agents and strong acids to prevent unwanted reactions. Shelf life is typically several years under recommended conditions.

B2B Procurement Guide

When procuring 2-acetophenone oxime, prioritize suppliers with verified certifications (e.g., ISO, GMP) to ensure quality and traceability. Request certificates of analysis (CoA) to confirm purity (commonly ≥98%). Bulk purchases may offer cost savings, but verify storage capacity. Logistics should account for its stability; avoid extreme temperatures during transit. For international shipments, ensure compliance with regional chemical regulations (e.g., REACH, TSCA). Sample testing before large-scale orders is advisable.
