With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Ethyl chloroacetate which has developed particularly rapidly in recent years. Do you know about Ethyl chloroacetate?
The official answer: Ethyl chloroacetate is an organic compound with the structural formula ClCH2COOC2H5. It is a colorless and transparent liquid. It has a pungent and irritating odor. It decomposes in hot water or alkali. Miscible with ethanol and ether, insoluble in water. Relative density (d204) 1.. freezing point -26&#;. Refractive index (n20D) 1.. flammable. Toxic, LD50 (rabbit, skin) 230 mg/kg. its vapor can strongly irritate the eyes and has tear-jerking properties. Used as raw material for pharmaceuticals and spices, also used as a solvent.
Substance identity
The &#;Substance identity&#; section is calculated from substance identification information from all ECHA databases. The substance identifiers displayed in the InfoCard are the best available substance name, EC number, CAS number and/or the molecular and structural formulas.
Some substance identifiers may have been claimed confidential, or may not have been provided, and therefore not be displayed.

The EC Number is the numerical identifier for substances in the EC Inventory. The EC Inventory is a combination of three independent European lists of substances from the previous EU chemicals regulatory frameworks (EINECS, ELINCS and the NLP-list). More information about the EC Inventory can be found here.
If the substance was not covered by the EC Inventory, ECHA attributes a list number in the same format, starting with the numbers 6, 7, 8 or 9.
The EC or list number is the primary substance identifier used by ECHA.
The CAS number is the substance numerical identifier assigned by the Chemical Abstracts Service, a division of the American Chemical Society, to substances registered in the CAS registry database. A substance identified primarily by an EC or list number may be linked with more than one CAS number, or with CAS numbers that have been deleted. More information about CAS and the CAS registry can be found here.
The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance. This information is only displayed if the substance is well&#;defined, its identity is not claimed confidential and there is sufficient information available in ECHA&#;s databases for ECHA&#;s algorithms to generate a molecular structure.
The molecular structure is based on structures generated from information available in ECHA&#;s databases. If generated, an InChI string will also be generated and made available for searching. This information is only displayed if the substance is well-defined, its identity is not claimed confidential and there is sufficient information available in ECHA&#;s databases for ECHA&#;s algorithms to generate a molecular structure.
