CATO CoA Upgrade：Professional Information at a Glance

Dear CATO Customers and Partners,

To continuously improve our services and provide you with more professional, detailed, and standardized product information,

CATO has upgraded the template for our Certificate of Analysis (CoA). The new certificate is now officially in use.

We always uphold the principle of "Make the Tests More Accurate", and we are committed to excellence in every detail.

This upgrade aims to make the certificate information more complete, the structure clearer, and the access more convenient, thereby supporting your research and analytical work more smoothly. Here are the key highlights of this revision:

Five Key Enhancements to Enhance Your Experience

1. Unified Header Information for Easier Retrieval and Filing

The new certificate clearly labels the product's

Catalog Number (CatNo.) andLot Number (Lot) in the header of every page. Whether you are viewing a multi-page digital document or organizing printed hard copies, you can instantly identify the corresponding product information on each page. This makes it easier to trace and file, eliminating the hassle of mixing up pages.

2. Enriched Home Page with New Key Experimental Informationn

We have added two highly-requested pieces of practical information to the home page of the new certificate:

Solubility: If relevant tests have been completed, we will now directly provide the product's solubility in different solvents. This offers a crucial reference for sample preparation before your experiments.

Shipping Condition: The certificate now clearly states the product's shipping temperature, ensuring you have a clear understanding of the storage requirements during transit.

3. Optimized Chemical Structure and Molecular Formula

We have made slight adjustments to the display of the

Molecular Formula

 to make it clearer and more intuitive, allowing you to quickly obtain accurate chemical information.

4. Increased Transparency and Traceability of qNMR Quantitative Data

For products calibrated using quantitative

NMR(qNMR), the new certificate now provides unprecedentedly detailed information.In addition to the final quantitative result, we have included the complete quantitative calculation formula and the detailed values for each parameter used in the formula at the end of the certificate. This includes information such as the sample weight, internal standard details, and internal standard weight. This enhancement significantly increases the transparency and traceability of our analytical results, making it easier for you to conduct in-depth technical reviews and confirmations.

5. Prominent Certification Marks to Showcase Professionalism and Authority

ISO 17034 is the gold standard for the competence of Reference Material Producers. The new certificate now features the

ANAB ISO:17034 international certification mark in the bottom right corner, further demonstrating the authority and reliability of CATO products.

This certificate upgrade is another step in CATO's pursuit of excellence and continuous improvement. Thank you for your trust and support. We are committed to being your most reliable partner in research and production and will continue to improve to provide you with the most reliable reference materials and professional services.
