In the realm of chemical synthesis, particularly for pharmaceutical applications, the quality and specifications of raw materials are paramount. Boc-Gly-Gly-OH, or N-(tert-Butoxycarbonyl)glycylglycine, is a prime example of a critical pharmaceutical intermediate where adherence to stringent quality standards directly impacts the success of downstream processes, most notably peptide synthesis.

The primary specification that researchers and manufacturers look for when they buy Boc-Gly-Gly-OH is its purity. Typically, a purity level of ≥98% is considered the standard for reliable performance in sensitive synthetic reactions. This high purity ensures that the desired reactions proceed with minimal interference from impurities, which could otherwise lead to the formation of unwanted byproducts or reduce the yield of the target peptide. Companies actively seek a dependable Boc-Gly-Gly-OH supplier China, often prioritizing those who provide detailed Certificates of Analysis (CoA) that verify purity through methods like High-Performance Liquid Chromatography (HPLC).

Another crucial specification relates to the physical characteristics of Boc-Gly-Gly-OH. It is consistently described as a white to off-white powder. Deviations from this appearance can sometimes indicate the presence of contaminants or degradation, highlighting the importance of proper storage and handling. The recommended storage condition of typically -15ºC (or sometimes 0-8ºC) in a tightly sealed container is essential for maintaining the compound's integrity and preventing moisture absorption, which can affect its reactivity.

The molecular formula (C9H16N2O5) and molecular weight (232.23 g/mol) are fundamental identifiers that confirm the identity of the compound. While these are constant, variations in reported melting points (often around 132-133°C or 128-133°C) can also serve as indicators of purity, with sharper melting ranges generally signifying higher purity.

For those engaged in peptide synthesis, understanding these specifications is not merely academic; it’s a practical necessity. The reliability of amino acid derivatives for research like Boc-Gly-Gly-OH directly impacts the efficiency and reproducibility of experiments and manufacturing processes. This is why selecting a trusted pharmaceutical intermediate supplier is so critical. They not only provide the chemical but also the assurance of quality that underpins successful drug development.

In conclusion, the quality specifications of Boc-Gly-Gly-OH—its purity, appearance, and storage requirements—are critical parameters that govern its performance in complex chemical syntheses. By paying close attention to these details and partnering with reputable suppliers, researchers and manufacturers can ensure the integrity of their peptide synthesis projects and advance the development of novel pharmaceutical solutions.
