For professionals in the chemical industry, a deep understanding of the properties of key intermediates is fundamental to successful product development and manufacturing. 4-Chloroacetoacetanilide (CAS 101-92-8), also known as Acetoacetic-p-chloroanilide, is one such vital compound. This article provides a detailed look at its physico-chemical properties, highlighting why these attributes make it so valuable for applications in pigments and pesticides.

The compound's molecular formula is C10H10ClNO2, with a molar mass of 211.645 g/mol. Visually, it appears as a white crystalline flaky powder, a form that facilitates handling and incorporation into various chemical processes. Its density is reported as 1.285 g/cm³, indicating a relatively compact molecular structure. These physical characteristics are important for process design and material handling.

Thermal properties are critical for determining a chemical's suitability for different manufacturing conditions. 4-Chloroacetoacetanilide exhibits a melting point in the range of 131-134°C. This relatively high melting point means it remains a solid at typical ambient temperatures, simplifying storage and transportation. The boiling point is significantly higher, around 400.5°C at 760 mmHg, suggesting good thermal stability and the ability to withstand elevated temperatures during synthesis reactions without significant decomposition.

Further important properties include its flash point, which is 196°C. A higher flash point generally indicates a reduced risk of ignition, contributing to safer handling practices. The vapor pressure at 25°C is very low (1.26E-06 mmHg), signifying minimal volatility under standard conditions. Its refractive index is 1.579, a property that can be relevant in certain specialized applications, though its primary value lies in its chemical reactivity.

The purity standard of 98.0% minimum is a testament to the rigorous manufacturing processes employed by reputable suppliers. This high purity is essential for achieving consistent results in downstream applications, particularly when synthesizing pigments where trace impurities can significantly alter color hue or performance. For pesticide synthesis, the precise chemical structure and purity are critical for the efficacy and safety of the active ingredients.

When seeking to purchase 4-Chloroacetoacetanilide, it is paramount to engage with suppliers who can reliably provide these specifications. Manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. prioritize quality control to ensure that each batch meets the high standards required by industries. Understanding these chemical properties empowers formulators and engineers to optimize their processes and develop superior end products. Whether it's for achieving vibrant colors in pigments or formulating effective agrochemicals, the detailed characteristics of 4-Chloroacetoacetanilide are key to success.
