Disodium Uridine Monophosphate
Overview
Disodium Uridylate (UMP-Na2) is the disodium salt of uridine 5'-monophosphate, a pyrimidine nucleotide. It plays a critical role in RNA synthesis and various metabolic pathways. As a nucleotide derivative, it is extensively used in biochemical and pharmaceutical research, particularly in studies related to RNA metabolism, enzyme mechanisms, and cell signaling. Its applications also extend to the food industry, where it serves as a flavor enhancer.
Physical and Chemical Properties
Disodium Uridylate appears as a white to off-white crystalline powder with high solubility in water and slight solubility in ethanol. It is hygroscopic and should be stored under controlled conditions to prevent degradation. The compound decomposes at temperatures above 200°C. Its molecular weight is 368.14 g/mol, and it is stable under recommended storage conditions, though prolonged exposure to light or moisture should be avoided.
Main Applications
In biochemical research, Disodium Uridylate is used as a substrate for enzymes involved in nucleotide metabolism and RNA synthesis. It is also employed in pharmaceutical formulations as an intermediate. In the food industry, it acts as a flavor enhancer, often combined with other nucleotides to create umami taste profiles. Its use is regulated, and it must meet specific purity standards for food-grade applications.
Safety and Storage
Disodium Uridylate should be handled with care to avoid inhalation or contact with skin and eyes. Personal protective equipment, including gloves and goggles, is recommended. Storage conditions are critical for maintaining stability. The compound should be kept in a cool, dry place (2-8°C), protected from light and moisture. Properly sealed containers are essential to prevent hygroscopic absorption.
B2B Procurement Guide
When procuring Disodium Uridylate, prioritize suppliers with verified certifications and a track record of reliability. Key factors include purity (≥98%), CAS number confirmation, and compliance with industry standards. Price ranges vary based on purity and supplier, but bulk purchases may offer cost advantages. Always request material safety data sheets (MSDS) and certificates of analysis (CoA) to ensure product quality and safety.
