Ethyl Methyl Carbonate (EMC), Battery Grade 500g

Chemical Name: Ethyl Methyl Carbonate
CAS Number: 623-53-0
Product Code: EL623-53-0
Grade: Battery Grade
Brand: Xnergy

Product Introduction

Ethyl methyl carbonate (EMC) is the asymmetric linear carbonate in the carbonate solvent family, occupying a performance midpoint between DMC and DEC. Its defining advantage is a melting point of −55°C — far below DMC’s 4°C — making it the preferred co-solvent for electrolyte formulations that must remain liquid and conductive at sub-zero temperatures. EC/EMC and EC/DMC/EMC ternary blends are standard in electric vehicle cells designed for cold-climate operation. Xnergy supplies battery-grade EMC with moisture and acid specifications matched to demanding Li-ion electrolyte requirements.

Key Features

• Low melting point (−55°C) — remains liquid at temperatures where DMC would freeze, enabling low-temperature electrolyte formulation
• Balanced viscosity — lower viscosity than DEC, slightly higher than DMC, suitable for wide-temperature blends
• Wide liquid range — excellent co-solvent for EC/EMC and EC/DMC/EMC ternary systems
• Purity ≥99% — high-purity formulation for reproducible cell performance
• H₂O ≤10 ppm / Acid ≤10 ppm — precise contamination control for LiPF₆-based electrolytes
• Flexible volumes — available from 1 kg for laboratory studies to bulk for production
