Chemical Structure
Description
The occurrence of 4-tert-Butylphenyl chlorothioformate is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-tert-Butylphenyl chlorothioformate (CAS 22857-48-3) is a high-purity analytical reference standard with the molecular formula C11H13ClOS and a molecular weight of 228.74 g/mol.
The molecular framework of 4-tert-Butylphenyl chlorothioformate (C11H13ClOS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 4-tert-Butylphenyl chlorothioformate 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.
