Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Methylpiperazine-1-carboximidamide hemisulfate.
4-Methylpiperazine-1-carboximidamide hemisulfate (CAS 28457-20-7), molecular formula C6H14N4H2O4S and molecular weight 240.28 g/mol, is a CATO reference standard with documented purity and traceability.
4-Methylpiperazine-1-carboximidamide hemisulfate (C6H14N4H2O4S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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-Methylpiperazine-1-carboximidamide hemisulfate 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.
