For professionals in chemistry, life sciences, and manufacturing, understanding the precise specifications of chemical compounds is fundamental to successful research, development, and production. This article delves into the key characteristics of 2-Methyl-3,4-dihydro-2H-pyran-3,4-diol, a significant organic intermediate identified by CAS 53657-42-4, providing insights for those looking to buy this material.

2-Methyl-3,4-dihydro-2H-pyran-3,4-diol is primarily recognized by its CAS number, 53657-42-4, and is typically supplied as a white crystal. A critical specification for this compound, especially when used in applications such as biological buffers or as a component in detection reagents, is its purity. Reputable manufacturers and suppliers, like those found in China, commonly guarantee a minimum purity of ≥98%. This high purity ensures that the compound will perform reliably in sensitive chemical reactions and formulations, minimizing unwanted side reactions or impurities in the final product.

The molecular formula of this organic intermediate is C6H10O3, with a molecular weight of approximately 130.14. These identifiers are crucial for stoichiometric calculations in synthesis and formulation work. When you consider purchasing 2-Methyl-3,4-dihydro-2H-pyran-3,4-diol, it’s important to verify that the supplier provides accurate molecular weight and formula information. Understanding the typical loss on drying, which is often specified as ≤2.0%, is also vital for accurate weighing and process control.

For procurement managers and researchers, obtaining a detailed specification sheet from the supplier is a standard practice before making a purchase. This document should outline all critical parameters, including appearance, purity assays (often confirmed by methods like HPLC or NMR), and any specific storage recommendations. Proper storage, typically in clean, dry, and cool places, away from direct sunlight and rain, is essential to maintain the integrity and shelf life of the compound, which is often rated at two years under optimal conditions. By thoroughly understanding these specifications, buyers can confidently buy 2-Methyl-3,4-dihydro-2H-pyran-3,4-diol and ensure its suitability for their intended applications.
