Reference hazards: Published SDS for approximately 70% aqueous ethylamine identify highly flammable liquid and vapor, severe skin burns and eye damage, toxicity in contact with skin, harm if swallowed or inhaled, and possible respiratory irritation. Confirm the applicable GHS categories, hazard statements, and labeling in the supplied-grade SDS.
Handling and storage: Use appropriate ventilation, ignition controls, and protective equipment specified in the SDS. Keep suitable containers closed in a cool, well-ventilated location away from heat and ignition sources. Confirm container compatibility and storage conditions for the supplied product.
Transport classification: Confirm the applicable UN number, proper shipping name, hazard class, and packaging requirements for the actual ethylamine concentration and transport mode. The reference assay is 70.72% w/w, so the nominal “70%” grade name alone is insufficient for assigning transport classification.
Documentation before ordering: Request the current supplied-grade SDS, relevant batch COA, and applicable dangerous goods transport information. Review these documents with the personnel responsible for site handling and shipment classification.
Ethylamine 70% Aqueous Solution CAS 75-04-7
Ethylamine 70% Aqueous Solution CAS 75-04-7 from Aure Chemical
Ethylamine, also known as monoethylamine or ethanamine (CAS 75-04-7), is a primary aliphatic amine with the structure CH₃CH₂NH₂. The product presented here is an industrial 70% aqueous solution used as a raw material for agrochemical intermediates, pharmaceutical intermediates, and other ethylamine-derived fine chemicals. Aure Chemical supports China chemical sourcing, product specification review, and international export coordination for this aqueous grade.
Procurement review should address ethylamine concentration, residual diethylamine and triethylamine, ethanol, ammonia, and color. The water-containing formulation must be compatible with the intended synthesis route.

The 0.01% value for unknown component(s) is retained from the COA remarks; no identity, specification, or analytical method is given for this entry. Ethylamine content is reported as a mass fraction in the aqueous product. A separate water analysis is not provided.
These results are provided for preliminary technical evaluation and do not establish guaranteed specifications for every shipment. Confirm the agreed ethylamine concentration, impurity limits, and applicable quality requirements with Aure Chemical, and request the relevant batch-specific Certificate of Analysis (COA) before ordering.
Application Overview of Ethylamine 70% Aqueous Solution
Agrochemical intermediates: Used as an ethylamine feedstock in selected agrochemical synthesis routes, including triazine herbicide chemistry. Suitability of the aqueous grade depends on the reaction conditions and process water balance.
Pharmaceutical and fine chemical intermediates: Provides a primary amine building block for preparing ethylamine-derived intermediates. Acceptance for a particular route depends on its concentration, impurity profile, and the purchaser's qualification requirements.
Organic synthesis: The primary amine group can participate in selected substitution, acylation, and other derivatization reactions to prepare N-ethyl compounds. Process evaluation should establish whether the reaction accepts an aqueous amine feed.
Residual diethylamine and triethylamine may be relevant to downstream impurity control. Evaluate their reported limits alongside ethanol, ammonia, and the required ethylamine charge when reviewing this grade for a synthesis process.
