FAQ - Technical & Supply Chain
-
Q:
What is Ethyl Carbamate, and is it the same as polyurethane?
A: Ethyl carbamate, CAS 51-79-6, is a discrete low-molecular-weight carbamate ester with formula C3H7NO2 and is also called urethane or carbamic acid ethyl ester. In this context, urethane is a synonym for the single compound; it is not a polyurethane resin or a normal polyurethane feedstock. -
Q:
What authorized uses should be confirmed for Ethyl Carbamate?
A: Ethyl carbamate may be requested for controlled chemical synthesis, analytical-reference work or other specifically authorized applications. It is not a general-purpose chemical and is not a normal resin raw material, so the buyer must confirm lawful intended use, local compliance and handling requirements before procurement. -
Q:
Which specifications should be checked when purchasing Ethyl Carbamate?
A: Confirm assay and method, appearance, melting range, water, residue, related impurities, residual solvents and any required trace-metal limits against the offered batch specification. Grade requirements depend on the application, so the quotation and product specification should use the same analytical basis. -
Q:
How should Ethyl Carbamate be stored, handled and shipped?
A: Store it in tightly closed, cool, dry, well-ventilated conditions away from incompatible materials and unauthorized use. Review the safety classification and destination regulatory controls before dispatch, and confirm suitable packaging, net quantity, labelling and required transport or compliance documents. -
Q:
What are the typical physical properties of Ethyl Carbamate?
A: Ethyl carbamate CAS 51-79-6, C3H7NO2 and molecular weight 89.09, is normally a colorless crystalline solid or white powder with a melting range near 48-51 C and a boiling point near 182-184 C. Reported density is about 0.986 g/cm3 and flash point about 92 C; confirm the actual batch specification and purity because analytical and synthesis grades can differ.
