Description
CATO manufactures Penicillamine Impurity 7 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.
Penicillamine Impurity 7 (CAS 63474-90-8) is a high-purity analytical reference standard with the molecular formula C7H15NO2SHCl and a molecular weight of 213.72 g/mol.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Penicillamine Impurity 7 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 213.72 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
