Are ECH and Epichlorohydrin the same product?

Yes. ECH is the common abbreviation for Epichlorohydrin. The product is also known as Chloromethyloxirane and 2-Chloro-1,2-epoxypropane, with CAS 106-89-8.

What specifications should buyers confirm before ordering Epichlorohydrin?

Buyers should confirm CAS identity, assay or purity grade, moisture, color, acidity or alkalinity, stabilizer or inhibitor status where applicable, and packaging requirements. A COA can be supplied for grade verification.

What are the key safety concerns when handling Epichlorohydrin due to its reactive nature?

Epichlorohydrin is a flammable liquid capable of forming explosive vapor-air mixtures. It is toxic by inhalation and skin absorption, and requires careful handling with proper PPE including chemical-resistant gloves and goggles. Storage should be in cool, ventilated areas away from ignition sources, strong acids/bases, and oxidizing agents. Refer to the latest SDS before handling.

What role does Epichlorohydrin play in epoxy resin manufacturing?

Epichlorohydrin is a key raw material in the production of epoxy resins. It reacts with bisphenol-A under alkaline conditions to form bisphenol-A diglycidyl ether (BADGE), the most common epoxy resin backbone. The epoxide group in ECH provides the reactive site for crosslinking reactions in cured epoxy systems, making it indispensable in coatings, adhesives, composites, and electronics encapsulation applications.

What storage conditions are critical for maintaining Epichlorohydrin stability?

Epichlorohydrin should be stored in a cool, dry, well-ventilated area below 30°C, away from direct sunlight. The container must be kept tightly sealed to prevent moisture ingress and vapor release. It is incompatible with strong acids, strong bases, oxidizing agents, and metal salts. Storage areas should be equipped with explosion-proof electrical systems due to the flammable nature of ECH vapors.

Epichlorohydrin (CAS 106-89-8)

Epichlorohydrin (ECH) CAS 106-89-8, also known as Chloromethyloxirane or 2-Chloro-1,2-epoxypropane, is a reactive chlorinated epoxide supplied as a 99.9% industrial chemical intermediate for epoxy resin production, polyether polyol processing, chlorohydrin rubber manufacturing, water treatment resin synthesis, and related organic synthesis routes. Its epoxide ring and chloromethyl group support polymerization, crosslinking, and functionalization reactions in controlled industrial processes. Standard packaging is 225 kg/drum or as required; COA, TDS, and SDS can be provided according to grade and order requirements.

Product Description

1 Product Overview

2 Product Information / Specifications

3 Physical & Chemical Properties

Product Overview

Epichlorohydrin is provided for industrial use as a reactive intermediate and basic chemical raw material. It is more appropriately positioned as an industrial synthesis intermediate rather than a finished formulation ingredient or consumer-facing product.

This product is commonly applied in epoxy resin manufacturing and other downstream reaction systems that require chlorinated epoxide functionality. Product selection is generally based on identity consistency, purity level, and compatibility with the intended synthesis route.
