CAS:27333-50-2
The product identified as CAS:27333-50-2 is a 5‑chloro‑1,3,3‑trimethyl‑1,3‑dihydrospiro[indole‑2,3′‑naphtho[2,1‑b][1,4]oxazine] photochromic compound. Its molecular formula is C22H19ClN2O and the molecular weight is 362.85 g mol‑1. The reported boiling point is 568.372 °C and the appearance is a beige fine powder. The supplier lists the material as a high‑performance spiro‑oxazine used in optical applications.
The compound is offered in research‑grade (typically 95‑99 % purity) and industrial‑grade (typically 99.5 % or higher) forms. Standard packaging for light‑sensitive chemicals includes amber‑glass vials of 100 g or sealed aluminium foil bags of 1 kg, both providing protection from UV exposure. Industry practice dictates storage at temperatures below 25 °C in a dark, dry environment to preserve photo‑chromic performance. The material exhibits fast colour‑change kinetics under UV light and shows excellent fatigue resistance, characteristics valued in smart‑window coatings.
Typical applications cover manufacture of photochromic lenses for eyewear, smart‑window coatings for automotive glass, and light‑responsive polymer systems. Buyers such as optical manufacturers, automotive suppliers and specialty coating firms source this chemical for research and production. The supplier ships the powder in sealed light‑protected packaging and advises confirmation of minimum order quantity, lead time and Incoterms before placing an order. Importers should also verify any required certifications or safety data sheets with the supplier.

Sourcing CAS:27333-50-2 from Tianjin Security Technology Development Ltd. Co. - China Import Guide
Before placing an order, importers should verify the supplier’s legal registration in Tianjin and confirm the existence of a valid business licence. Request copies of the company’s tax registration and any third‑party audit reports to assess operational credibility. Because the listed response rate is zero, establish a clear communication channel and obtain written confirmation of product specifications and pricing. It is also prudent to ask for a recent certificate of analysis for the specific batch to ensure the declared purity matches your requirements.
Shipping terms are not stated, so buyers must agree on Incoterms such as FOB Tianjin or CIF a destination port before finalising the contract. Clarify the expected lead time for production and packaging, especially if the order requires custom packaging for light protection. Payment methods commonly used in Chinese chemical trade include T/T in advance, L/C at sight or documentary collection; the preferred method should be confirmed with the supplier. Ensure that any freight forwarder is aware of the powder’s sensitivity to light and temperature to avoid damage in transit.
Arrange for an independent third‑party inspection of the batch prior to shipment, focusing on purity, moisture content and particle size distribution. Request the full safety data sheet, certificate of analysis and any relevant compliance documents such as REACH registration. Upon arrival, conduct a visual check for packaging integrity and perform a quick UV exposure test to confirm the compound’s photo‑chromic response. Maintaining records of these checks will support customs clearance and future quality assurance.
