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 5-[Bromoacetamido]tetramethylrhodamine.
CATO supplies 5-[Bromoacetamido]tetramethylrhodamine (CAS 166442-38-2), a certified reference material (molecular formula C26H24BrN3O4, MW 522.39 g/mol) for analytical method development and quality control.
The molecular framework of 5-[Bromoacetamido]tetramethylrhodamine (C26H24BrN3O4) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 5-[Bromoacetamido]tetramethylrhodamine 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.
