The Guanfacine hydrochloride, with the CAS registry number 29110-48-3,is also known as N-(Aminoiminomethyl)-2,6-dichlorophenylacetamide monohydrochloride. It belongs to the product categories of Amines;Intermediates & Fine Chemicals;Pharmaceuticals;Adrenoceptor. This chemical's molecular formula is C9H9Cl2N3O.HCl and molecular weight is 282.55.Its EINECS number is 249-443-3. What's more,Its systematic name is Benzeneacetamide, N-(aminoiminomethyl)-2,6-dichloro-,monohydrochloride. It is a centrally acting antihypertensive agent. The drug lowers both systolic and diastolic blood pressure by activating the central nervous system alpha-2 adrenoreceptors, which results in reduced sympathetic outflow leading to reduced vascular tone. Its adverse reactions include dry mouth, sedation, and constipation.
