Chemical Structure
Description
2-Methyl-2-propane-d9-thiol (CAS 99224-24-5) is a high-purity analytical reference standard with the molecular formula C4HD9S and a molecular weight of 99.24 g/mol.
Structurally, 2-Methyl-2-propane-d9-thiol (C4HD9S) contains deuterium isotope labeling, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 99.24 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 2-Methyl-2-propane-d9-thiol 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.
