Chemical Structure
Description
The occurrence of Methyl-<SUP>13</SUP>C,d<SUB>3</SUB>-sulfonyl chloride is closely related to deuterium isotope labeling, a sulfone group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Methyl-<SUP>13</SUP>C,d<SUB>3</SUB>-sulfonyl chloride (CAS 1216581-01-9), a certified reference material (molecular formula [13C]D3ClO2S, MW 118.56 g/mol) for analytical method development and quality control.
Methyl-<SUP>13</SUP>C,d<SUB>3</SUB>-sulfonyl chloride ([13C]D3ClO2S) contains deuterium isotope labeling, a sulfone group, 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.
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.
As a certified reference material (CRM), Methyl-<SUP>13</SUP>C,d<SUB>3</SUB>-sulfonyl chloride 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.
