Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(Piperazin-1-yl)quinazoline dihydrochloride.
CATO supplies 4-(Piperazin-1-yl)quinazoline dihydrochloride (CAS 853681-18-2), a certified reference material (molecular formula C12H14N4HCl, MW 250.73 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 4-(Piperazin-1-yl)quinazoline dihydrochloride is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 250.73 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4-(Piperazin-1-yl)quinazoline dihydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
