The vibrant world of color, from textiles to cosmetics, is built upon a foundation of sophisticated organic chemistry. Within this realm, chemical intermediates play an indispensable role, serving as the foundational molecules from which complex dyes and pigments are synthesized. One such crucial intermediate, particularly relevant to the hair dye and broader pigment & dyestuff industries, is 5-[(2-Hydroxyethyl)Amino]-o-Cresol, identified by its CAS number 55302-96-0. Understanding its chemical nature and application is vital for chemists and procurement specialists in this field.

Chemically, 5-[(2-Hydroxyethyl)Amino]-o-Cresol is a substituted phenol derivative. Its molecular formula, C9H13NO2, and molecular weight of approximately 167.21 g/mol, provide essential clues about its reactivity. The presence of a hydroxyl group (-OH) on the aromatic ring and an amino group (-NH-) with an attached hydroxyethyl chain (-CH2CH2OH) equips this molecule with multiple reactive sites. These functional groups are key to its utility in dye synthesis, particularly in oxidative coupling reactions that form chromophores responsible for color.

As a hair dye intermediate, its role is primarily in permanent hair coloring. In this application, it acts as a coupler or a primary intermediate that reacts with developer molecules in the presence of an oxidizing agent. This process generates large dye molecules that become trapped within the hair shaft, providing long-lasting color. The specific shade achieved is dependent on the precise formulation and the combination of other intermediates used. For manufacturers looking to buy 5-[(2-Hydroxyethyl)Amino]-o-Cresol, its consistent reactivity is a primary consideration.

Beyond personal care applications, this compound serves as a versatile building block in the broader pigment and dyestuff sector. Its structure allows for further chemical modifications, enabling the synthesis of a wide array of coloring agents for textiles, inks, and coatings. The ability to fine-tune the molecular structure of such intermediates leads to dyes with specific properties, such as enhanced lightfastness, wash resistance, or particular color hues. Sourcing this intermediate from a reliable chemical manufacturer in China ensures access to a consistent supply chain for these specialized syntheses.

The synthesis of 5-[(2-Hydroxyethyl)Amino]-o-Cresol itself typically involves the reaction of 5-amino-o-cresol with ethylene oxide. Optimizing this reaction for yield and purity is a hallmark of skilled chemical production. Manufacturers who employ advanced synthesis techniques and rigorous quality control measures are able to produce material with purity levels as high as ≥99.0%. This high purity is essential for downstream applications where trace impurities could compromise the final dye or pigment's performance and safety profile.

For businesses in the chemical industry seeking to procure 5-[(2-Hydroxyethyl)Amino]-o-Cresol, engaging with experienced manufacturers is key. They can provide detailed technical specifications, understand the intricacies of dye synthesis, and offer competitive pricing for bulk orders. Whether you are developing new pigments, advanced textile dyes, or innovative hair coloring formulations, securing a reliable supply of this fundamental intermediate from a trusted supplier is a critical step towards achieving your product development and commercialization goals.
