Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Bromoacetamido-dPEG <SUP>®</SUP><SUB>11</SUB>-azide.
Bromoacetamido-dPEG <SUP>®</SUP><SUB>11</SUB>-azide (CAS 2172677-17-5), molecular formula C26H51BrN4O12 and molecular weight 691.61 g/mol, is a CATO reference standard with documented purity and traceability.
Bromoacetamido-dPEG <SUP>®</SUP><SUB>11</SUB>-azide (C26H51BrN4O12) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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 Bromoacetamido-dPEG <SUP>®</SUP><SUB>11</SUB>-azide 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.
