Guanfacine

同義語： N-(Aminoiminomethyl)-2,6-dichlorobenzeneacetamide, Guanfacine hydrochloride, Estulic, Tenex, Intuniv, 29110-47-2

Guanfacine has become a molecule of interest for formulators targeting noradrenergic signaling, particularly in the wake of demand for non-stimulant options in ADHD therapy and adjunctive treatments for hypertension. Its selectivity for alpha-2A adrenergic receptors sets it apart from older centrally acting antihypertensives, and this pharmacological edge drives steady sourcing from pharmaceutical and research buyers.

Chemically, guanfacine is a dichlorophenylacetamide derivative that functions as a centrally acting alpha-2 adrenergic agonist. The compound is synthesized through a multi-step route starting from 2,6-dichlorobenzeneacetic acid, yielding the free base or its hydrochloride salt depending on the intended formulation. Its ability to modulate norepinephrine release without the sedative burden of clonidine has positioned it as a preferred API for extended-release dosage forms.

LyvBio supplies guanfacine with a minimum assay of 99.0% (HPLC), suitable for both generic drug development and reference standard applications. Each batch is manufactured under cGMP conditions, with full traceability from raw material to final packaging. The product is available in kilogram to multi-ton quantities, supported by comprehensive documentation for regulatory filings.

製品の概要と成分

Guanfacine is a white to off-white crystalline powder with a molecular weight of 246.09 g/mol. It is freely soluble in water and methanol, making it adaptable to a range of oral solid and liquid formulations. The compound is typically supplied as the free base or hydrochloride salt, with the free base form offering flexibility for salt selection during early development.

The active pharmaceutical ingredient is characterized by a high degree of purity, with related substances controlled to stringent limits. This ensures consistent performance in both immediate-release and extended-release matrices, where even minor impurities can affect release kinetics.

Applications & Product Lines
