In the specialized world of chemical manufacturing and pharmaceutical development, the term 'purity' is not just a descriptor; it's a fundamental requirement that underpins the integrity and efficacy of final products. For intermediates like 8-(Benzyloxy)-5-(oxiran-2-yl)quinolin-2(1H)-one, identified by CAS number 173140-90-4, maintaining high purity levels, such as 98%, is paramount for its successful application.

This specific quinolinone derivative, appearing as a white to off-white crystalline powder, is frequently sought after by R&D scientists and procurement managers for its role in complex organic synthesis and as a pharmaceutical intermediate. The presence of impurities, even in small quantities, can lead to a cascade of issues in downstream processes. These can include reduced reaction yields, formation of unwanted by-products, difficulty in purification of the final API, and, in the worst-case scenarios, compromised safety and efficacy of the drug itself. Therefore, when searching for 'buy 8-(Benzyloxy)-5-(oxiran-2-yl)quinolin-2(1H)-one' or its synonyms, prioritizing suppliers who explicitly state and guarantee high purity is essential.

Manufacturers specializing in fine chemicals and pharmaceutical intermediates, particularly those in China, understand this critical demand. They invest heavily in advanced analytical techniques and stringent quality control measures to ensure that products like CAS 173140-90-4 consistently meet specifications. This dedication to quality allows businesses to confidently purchase 'wholesale C18H15NO3' knowing they are receiving a reliable material for their production needs. The ability to procure such high-purity compounds at competitive prices from established suppliers is a significant advantage for companies looking to optimize their operational costs without sacrificing quality.

For procurement professionals, requesting a Certificate of Analysis (CoA) that details the purity and impurity profile of the chemical intermediate is a standard practice. This document serves as proof of quality and helps ensure compliance with regulatory requirements. When engaging with a 'CAS 173140-90-4 supplier', asking for a sample and its accompanying CoA is a prudent step to verify the quality before committing to larger orders. Ultimately, the investment in high-purity intermediates directly translates to greater efficiency, reduced risk, and superior outcomes in pharmaceutical development and advanced chemical research.
