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 (R)-(1-hydroxy-1,1-diphenylpropan-2-yl)carbamate.
Tert-butyl (R)-(1-hydroxy-1,1-diphenylpropan-2-yl)carbamate (CAS 223906-32-9), molecular formula C20H25NO3 and molecular weight 327.42 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Tert-butyl (R)-(1-hydroxy-1,1-diphenylpropan-2-yl)carbamate (C20H25NO3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 (R)-(1-hydroxy-1,1-diphenylpropan-2-yl)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.
