In the complex world of chemical supply chains, accurate identification and quality assurance are non-negotiable. NINGBO INNO PHARMCHEM CO.,LTD. places significant emphasis on these aspects, particularly when dealing with specialized compounds like Reactive Orange 16, identified by CAS number 20262-58-2.
The CAS (Chemical Abstracts Service) Registry Number is a unique numerical identifier for chemical substances. For Reactive Orange 16, this number, 20262-58-2, serves as a universal reference point, eliminating ambiguity and ensuring that all parties in the supply chain – from manufacturers to end-users – are referring to the exact same compound. This is crucial for maintaining product integrity, especially when the chemical has diverse applications, such as being a high purity azo dye for textiles and also a pharmaceutical intermediate.
NINGBO INNO PHARMCHEM CO.,LTD. leverages this standardized identification to guarantee the quality of the Brilliant orange 3R we supply. Our rigorous quality control processes begin with ensuring that the CAS number aligns with the chemical's exact specifications, including its purity (typically 99%) and composition. This meticulous approach prevents costly errors and ensures that our clients receive the precise material required for their processes.
For businesses looking to buy Brilliant orange 3R, working with a reputable reactive orange 16 supplier China like NINGBO INNO PHARMCHEM CO.,LTD. means benefiting from this inherent quality assurance. We understand that whether the application is textile dyeing or pharmaceutical synthesis, the reliability of the chemical supplied is paramount. Our commitment is to provide clear, accurate information and consistently high-quality products, backed by the certainty of correct CAS number identification.
We encourage all our partners and potential clients to prioritize CAS number verification and to partner with suppliers who share our dedication to transparency and quality in chemical distribution.
