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 tert-Butyl (2-chloro-3-nitrophenyl)carbamate.
tert-Butyl (2-chloro-3-nitrophenyl)carbamate (CAS 905438-48-4) is a high-purity analytical reference standard with the molecular formula C11H13ClN2O4 and a molecular weight of 272.68 g/mol.
The molecular framework of tert-Butyl (2-chloro-3-nitrophenyl)carbamate (C11H13ClN2O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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 tert-Butyl (2-chloro-3-nitrophenyl)carbamate 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.
