CAS:144582-55-8
CAS:144582-55-8, supplied by Tianjin Security Technology Development Ltd. Co., is a photochromic compound with the chemical name Spiro[2H-indole-2,3'-[3H]naphth[2,1-b][1,4]oxazine], 5-chloro-1,3-dihydro-1,3,3-trimethyl-6'-(1-piperidinyl)-. This specialty chemical is used in applications requiring light-sensitive materials, such as photochromic lenses, inks, and coatings. Its molecular structure enables reversible color changes upon exposure to UV light.
The compound has a molecular formula of C27H28ClN3O and a predicted boiling point of 658.9°C at 760 mmHg. Its density is approximately 1.28 g/cm³, and it exhibits a refractive index of 1.669, which are critical for optical applications. The flash point is predicted at 352.3°C, indicating thermal stability under typical processing conditions. These properties make it suitable for integration into polymer matrices for durable photochromic products.
Industries such as eyewear, automotive, and security printing source this compound for its rapid response to UV exposure and fade back to clear in the absence of light. Buyers should confirm the purity, UV-Vis absorption spectrum, and compatibility with their base materials. The compound is typically supplied in powder form and may require custom packaging for light-sensitive handling.

Sourcing CAS:144582-55-8 from Tianjin Security Technology Development Ltd. Co. - China Import Guide
Before ordering CAS:144582-55-8 from Tianjin Security Technology Development Ltd. Co., verify the compound’s purity and UV-Vis absorption spectrum to ensure it meets the performance requirements for your application. Request a certificate of analysis and, if possible, a sample for testing in your specific polymer matrix or formulation.
Logistics for photochromic compounds require special attention due to their light-sensitive nature. Confirm that the supplier uses opaque, sealed packaging and can ship via air or sea with temperature control if needed. Discuss incoterms such as FOB Tianjin and lead times, as specialty chemicals may have longer production or handling requirements.
Quality checks should include testing the photochromic response under UV light, as well as evaluating compatibility with your base materials. Inspect all documentation, including MSDS and COA, upon receipt to ensure compliance with your industry standards. For optical applications, validate the refractive index and clarity in a prototype before full-scale production.
