For industries reliant on high-quality chemical inputs, understanding the precise specifications of raw materials like Calcium 3-Hydroxybutyrate (CAS 51899-07-1) is non-negotiable. Whether used as a pharmaceutical intermediate or a key component in nutritional supplements, the quality of this white powder directly impacts product safety, efficacy, and regulatory compliance. This guide highlights the essential quality parameters buyers should consider when looking to purchase.

The primary specification for Calcium 3-Hydroxybutyrate is its assay, which indicates the purity of the compound. For most pharmaceutical and nutritional applications, an assay of 98% to 102% is considered standard. This range ensures that the majority of the material is the desired compound, minimizing the presence of unwanted impurities that could interfere with downstream processes or affect the final product's performance. Manufacturers must consistently meet these assay requirements.

Beyond the assay, several other parameters are crucial. Loss on drying (LOD) is important, indicating the amount of volatile matter, primarily water, in the sample. A low LOD, typically ≤1.00%, suggests a well-dried product, contributing to its stability and shelf life. The pH value, usually within the range of 7.4 to 8.4, is also a key indicator of the product's chemical environment and can be important for formulation compatibility. The specific percentage of Calcium (Ca) and 3-Hydroxybutyrate in the compound are also vital for stoichiometric calculations and formulation accuracy.

When purchasing Calcium 3-Hydroxybutyrate, buyers should always request a Certificate of Analysis (CoA) from the manufacturer. This document formally outlines the results of quality control tests for a specific batch, confirming that it meets the agreed-upon specifications. For those looking to buy in bulk or establish long-term supply agreements, understanding the manufacturer's quality management system and their process for handling deviations is equally important.

Reputable suppliers and manufacturers of Calcium 3-Hydroxybutyrate will not only provide these detailed specifications but also offer technical support to help clients understand how these parameters relate to their specific applications. By prioritizing these quality aspects and working with trusted sources, pharmaceutical and nutritional product developers can ensure the integrity and success of their formulations.
