The global chemical market is dynamic, with certain intermediates commanding significant attention due to their critical applications. 6,7-Dimethoxyquinazoline-2,4-dione (CAS 28888-44-0) is one such compound, highly sought after by the pharmaceutical industry. Its utility as a precursor for antihypertensive drugs and as a reference standard for impurities makes understanding its market dynamics essential for procurement professionals. Key considerations for buyers include product price, purity levels, and the reliability of suppliers.

When looking to buy 6,7-Dimethoxyquinazoline-2,4-dione, buyers often compare offerings from various regions. China has emerged as a major hub for chemical manufacturing, offering a competitive edge in both cost and production volume. Many Chinese manufacturers specialize in producing high-purity intermediates like CAS 28888-44-0, often at more attractive prices than those found in other global markets. This makes sourcing from China a strategic advantage for many pharmaceutical companies.

Purity is a non-negotiable aspect when sourcing this compound for pharmaceutical use. Standard specifications often require a purity of ≥98% (HPLC) or higher. Buyers should always request a detailed Certificate of Analysis (CoA) from their potential supplier to verify the product's quality and composition. This document typically includes information on assay, related substances, residual solvents, and other critical parameters that impact the suitability of the compound for API synthesis.

The price of 6,7-Dimethoxyquinazoline-2,4-dione can vary based on factors such as order volume, purity grade, and current market supply-demand conditions. Bulk purchases generally result in lower per-unit costs. It is advisable to obtain multiple quotes from different manufacturers and suppliers to ensure competitive pricing while not compromising on quality. Furthermore, building a relationship with a trusted supplier can lead to more favorable terms and consistent availability.

In summary, for businesses requiring 6,7-Dimethoxyquinazoline-2,4-dione, a strategic approach to sourcing is crucial. Leveraging the competitive advantages offered by Chinese manufacturers and suppliers, while prioritizing stringent purity standards and requesting comprehensive documentation, will ensure a reliable and cost-effective procurement process for this vital pharmaceutical intermediate.
