It belongs to the family of 4-dimethylaminoazobenzene derivatives, a group of historical importance in the study of azo dyes and chemical toxicology. In the laboratory it serves as a reference material and test substance for research work, and as a non-heterocyclic building block for the synthesis of coloured and photoresponsive molecules.\u003c\/p\u003e\n\u003cp\u003eThe properties that determine its usefulness are rooted in the donor–acceptor conjugated system within the molecule. The dimethylamino group acts as a strong electron-donating substituent that works in combination with the electron-withdrawing azo bridge, producing strong absorption in the visible region and the bright colour characteristic of azo dyes. The azo bond can also isomerise between trans and cis forms under irradiation, a fundamental property exploited in molecular switch research. Placing the chlorine atom at the ortho position introduces steric hindrance and electronic effects different from those of the para isomer, so the compound is frequently used for comparative studies.\u003c\/p\u003e\n\u003cp\u003eIn Indonesian laboratories, this material fits naturally into university research groups and institutional laboratories working on synthetic organic chemistry, dye chemistry, and photochemistry. It is typically handled in small quantities on the bench for structure–property comparisons across substituted azobenzenes, or drawn on as a starting material in multi-step preparations. Its role as a reference and comparison substance also makes it useful in analytical method development work where a well-defined coloured compound is required.\u003c\/p\u003e\n\u003ch3\u003eLaboratory Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNon-heterocyclic building block for synthesis: the intact azo scaffold with its reactive dimethylamino and chlorinated ring positions allows chemists to construct larger coloured target molecules without building the azo linkage themselves.\u003c\/li\u003e\n\u003cli\u003eAzo dye chemistry research: as a member of the 4-dimethylaminoazobenzene family, it provides a well-characterised donor–acceptor system for investigating how substituents govern colour and visible absorption behaviour.\u003c\/li\u003e\n\u003cli\u003ePhotoresponsive and molecular switch studies: the trans–cis isomerisation of the azo bond under irradiation makes this compound a practical model system for research into light-driven molecular switching.\u003c\/li\u003e\n\u003cli\u003eComparative substituent-effect studies: the ortho chlorine placement gives steric hindrance and electronic character distinct from the para isomer, making it a direct comparison standard against related azobenzene derivatives.\u003c\/li\u003e\n\u003cli\u003eReference and test substance in research: its defined structure and history within toxicological and dye studies allow it to serve as a comparison material during method development and laboratory investigation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: TCI\u003c\/li\u003e\n\u003cli\u003eCAS number: 3010-47-7\u003c\/li\u003e\n\u003cli\u003eCatalogue number: C0157\u003c\/li\u003e\n\u003cli\u003eCategory: Chemistry \u0026gt; Building Blocks \u0026gt; Non-Heterocyclic Building Blocks\u003c\/li\u003e\n\u003cli\u003ePack sizes: available in the standard research-scale pack sizes offered by TCI for this catalogue item\u003c\/li\u003e\n\u003cli\u003eStorage: keep in a tightly closed container, protected from light, and stored under the conditions stated on the manufacturer's label\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHandling and Storage\u003c\/h3\u003e\n\u003cp\u003eStore the container tightly closed in a cool, dry, well-ventilated area away from direct sunlight, since the azo bond is light-sensitive and can isomerise on exposure to irradiation. Amber glass bottles or the original manufacturer packaging are suitable, and the material should be kept apart from strong oxidising agents and sources of ignition. Handle in a fume hood using gloves, safety glasses, and a laboratory coat, and avoid generating or inhaling dust when weighing out the solid. As with all azo dye derivatives of this class, minimise skin contact, wash hands after handling, and consult the manufacturer's safety data sheet before use and before disposing of residues or contaminated materials.\u003c\/p\u003e","brand":"TCI","offers":[{"title":"25g","offer_id":48085974352090,"sku":"TCI2510C015714126","price":4347000.0,"currency_code":"IDR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0756\/7156\/8602\/files\/TCI2510C0157.jpg?v=1767094787","url":"https:\/\/amiscientific.com\/en\/products\/tci2510c015714126","provider":"AMI Scientific","version":"1.0","type":"link"}
