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 1-(5-Chlorothiophen-2-yl)-2-methylpropan-2-ol.
1-(5-Chlorothiophen-2-yl)-2-methylpropan-2-ol (CAS 887576-13-8), molecular formula C8H11ClOS and molecular weight 190.69 g/mol, is a CATO reference standard with documented purity and traceability.
1-(5-Chlorothiophen-2-yl)-2-methylpropan-2-ol (C8H11ClOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
