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 (4-chloro-2-hydroxyphenyl)carbamate.
tert-Butyl (4-chloro-2-hydroxyphenyl)carbamate (CAS 937064-33-0) is a high-purity analytical reference standard with the molecular formula C11H14ClNO3 and a molecular weight of 243.69 g/mol.
The molecular framework of tert-Butyl (4-chloro-2-hydroxyphenyl)carbamate (C11H14ClNO3) 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 its high hydrophobicity (logP), 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.
As a certified reference material (CRM), tert-Butyl (4-chloro-2-hydroxyphenyl)carbamate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
