Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Buta-1,3-diene-1-sulfonyl chloride (CAS 176697-78-2), a certified reference material (molecular formula C4H5ClO2S, MW 152.60 g/mol) for analytical method development and quality control.
Based on its molecular formula C4H5ClO2S, Buta-1,3-diene-1-sulfonyl chloride contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 152.60 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), Buta-1,3-diene-1-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.
