Dichloromethane Extrapure
Dichloromethane Extrapure Supplier
Dichloromethane (DCM), commonly referred to as methylene chloride, is a volatile, clear, colorless organochlorine liquid widely recognized for its high solvency power and low boiling point. Because it dissolves a broad spectrum of organic compounds while remaining immiscible with water, it serves as a foundational solvent across scientific and manufacturing environments.
In high-precision applications, solvent purity directly governs process safety, reaction yields, and analytical accuracy. Even minute traces of stabilizers, residual non-volatile matter, acidity, or moisture can skew chromatographic baselines, poison sensitive catalysts, or generate unwanted side products during chemical synthesis. This is where selecting an extrapure grade becomes critical. Extrapure Dichloromethane is processed and tested to limit background impurities, delivering the reliability needed for analytical protocols, quality control testing, and specialized synthesis.
Typical sectors relying on high-purity dichloromethane include pharmaceutical manufacturing, contract research organizations (CROs), academic laboratories, and fine chemical facilities. Procuring this material requires an established distribution network that understands industrial compliance, batch integrity, and material safety. As a dedicated chemical supplier and distribution partner, Omsys India assists enterprises in procuring reliable laboratory and process chemicals, functioning as a dependable Dichloromethane Extrapure Supplier for operations that require steady sourcing and transparent batch documentation.
What Is Dichloromethane Extrapure?
Dichloromethane is an organohalogen compound with the chemical formula CH2Cl2. It is characterized by its sweet, chloroform-like odor, relatively high density, and low boiling point (approximately 39.6°C).
- Chemical Name: Dichloromethane / Methylene Chloride
- IUPAC Name: Dichloromethane
- Molecular Formula: CH2Cl2
- CAS Number: 75-09-2
- Molar Mass: 84.93 g/mol
- Appearance: Clear, colorless, mobile liquid
The designation “extrapure” defines a chemical grade that surpasses standard technical or commercial grades in clarity, assay consistency, and impurity control. Unlike commercial-grade methylene chloride—which is often utilized in bulk paint stripping or foam manufacturing where minor hydrocarbons or acid traces are tolerable—extrapure-grade material is refined to control:
- Non-volatile residue: Preventing post-evaporation deposition on equipment or extracted analytes.
- Free acidity and chlorides: Protecting sensitive substrates and reducing equipment corrosion.
- Moisture content: Ensuring moisture-sensitive chemical reactions proceed without interference.
Why Choose Extrapure-Grade Dichloromethane?
For research institutions, analytical facilities, and intermediate manufacturers, grade selection affects operational predictability. Utilizing technical solvents in sensitive workflows frequently results in failed quality tests, re-runs, and lost processing time.
Choosing an extrapure grade offers distinct technical advantages:
- Reproducible Analytical Results: Analytical workflows require solvents with low baseline background interference. Extrapure-grade DCM minimizes spurious peaks in testing and ensures consistent spectrophotometric and chromatographic runs.
- Batch-to-Batch Uniformity: Regulated operations depend on steady feedstock properties. Controlled distillation and impurity screening ensure minimal variance between consecutive supply lots.
- Compatibility with Sensitive Chemistries: Low trace moisture and minimal free acid levels protect fragile reaction pathways, particularly in active pharmaceutical ingredient (API) development and organic synthesis.
- Traceability and Quality Verification: Authentic laboratory-grade and analytical-grade solvent batches are accompanied by traceable documentation, ensuring facility auditors and quality assurance teams can verify origin and batch performance against release specifications.

Applications of Dichloromethane Extrapure
Because of its strong solvency and ease of removal by evaporation, extrapure dichloromethane serves multiple analytical, pharmaceutical, and production roles:
Laboratory Solvent & Analytical Testing
Extrapure DCM is commonly employed as a laboratory solvent in sample preparation, liquid-liquid extraction, and column chromatography. Its low boiling point allows for rapid solvent recovery and concentration of delicate analytes without subjecting them to excessive thermal degradation.
Pharmaceutical & Intermediate Processing
Pharmaceutical synthesis teams employ high-purity dichloromethane as a reaction medium for chemical transformations where polar aprotic conditions are necessary. It is also utilized in crystallization, purification, and extraction steps for active compounds, subject to residual solvent validation under relevant pharmacopeial guidelines (e.g., ICH Class 2 limits).
Chemical Synthesis & Research
In organic research, DCM provides an inert, low-temperature reaction solvent for chlorination, acylation, and esterification workflows. Its low chemical reactivity with common electrophiles makes it an effective medium across university, institutional, and industrial research settings.
Precision Cleaning & Industrial Formulations
Where specialized industrial components, electronic substrates, or optical assemblies require thorough degreasing without leaving particulate or oily residues, extrapure solvent grades are used instead of crude industrial distillates.
How to Select a Reliable Dichloromethane Extrapure Supplier
Selecting an industrial or analytical chemical distributor requires systematic vendor vetting. For procurement officers, quality control heads, and laboratory managers, key supplier evaluation criteria include:
- Verified Product Grade & CoA: A competent partner must provide an authentic, batch-specific Certificate of Analysis displaying tested assay values, water content, and residue levels prior to dispatch.
- Safety Data Sheet (SDS) Compliance: Standardized SDS documentation covering physical hazards, GHS pictograms, PPE requirements, and first-aid measures must accompany material shipments.
- Traceability & Packaging Integrity: Containers must be chemically compatible with chlorinated solvents, sealed against vapor loss, and labeled with clear batch numbers and expiry or re-test dates.
- Supply Continuity: A dependable Dichloromethane Extrapure Supplier must demonstrate inventory stability, managing recurring schedule demands without abrupt stockouts or extended lead times.
- Logistics & Regulatory Transport: Solvents classified as hazardous substances require transporters equipped for compliant handling, segregation, and regional transit documentation.
